A 90-degree angle, also known as a right angle, is an angle that measures exactly 90 degrees.
A 90-degree angle is an angle that measures exactly 90 degrees. It is also known as a right angle, since it is an angle that forms a right angle.
In geometry, angles are measured in degrees, and a full rotation is equal to 360 degrees. The angle formed by two intersecting lines is measured by the amount of rotation needed to bring one line to overlap the other. A 90-degree angle is formed by rotating one line by exactly 90 degrees, so that the two lines form a right angle.
A right angle is an angle that measures 90 degrees and it is represented by a small square at the angle's vertex. This square is a symbol of the angle's measure. In addition, the right angle is the only angle that can be used in geometry to create perpendicular lines which are lines that meet at 90 degrees.
In real-world applications, right angles are found in many things such as the corners of a room, the corners of a square or rectangle, and the corners of tools like a square, a ruler, and a protractor.
Therefore, In short, a 90-degree angle, also known as a right angle, is an angle that measures exactly 90 degrees. It's represented by a small square at the angle's vertex, and it's the only angle that can be used in geometry to create perpendicular lines.

What is a fraction?
In mathematics, a fraction is represented by a number that identifies a portion of a whole. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.
We are given 0.5 which is to be converted into a fraction.
So, for this we will take 0.5 as the numerator and 1 as the denominator because anything divided by 1 is the number itself.
Thus, we get
⇒0.5/1
Now, we will multiply both numerator and denominator by 10.
From this, we get
⇒(0.5*10)/(1*10)
⇒5/10
Now, we will reduce the fraction to the lowest form by dividing both numerator and denominator by 5.
From this, we get the fraction as 1/2.

How do you use the substitution method with three variables?.
The substitution method is a powerful tool used to solve systems of linear equations with three variables. Beginning with one of the equations for one of the variables, utilise the substitution method.
This will give you an expression for that variable in terms of the other two. Then, substitute this expression into the other equations and solve for the remaining variables.
Consider, for example, a set of linear equations involving the variables x, y, and z:
x + y + z = 13
2x + 4y - z = 6
3x - 2y + 3z = 11
Start by solving the first equation for x in order to apply the substitution method here:
x = 13 - y - z
Now solve for y and z by substituting this expression into the previous two equations:
2(13 - y - z) + 4y - z = 6
39 - 2y + 3z = 6
3(13 - y - z) - 2y + 3z = 11
39 - 5y + 6z = 11
Subtract 39 from both sides of each equation, then solve for y and z using elimination or another method. Once you have found values for both variables, plug them into the original expression for x to find its value.

A phone company offers two monthly plans. Plan A costs $40 plus an additional $0.02 for each minute of calls. Plan B has no initial fee but costs $0.18 for each minute of calls. What is the cost when the two plans cost the same for a set number of minutes?
The cost of plan A is represented by the equation:
Cost A = 40 + 0.02x
where x is the number of minutes of calls.
The cost of plan B is represented by the equation:
Cost B = 0.18x
To find the point where the two plans cost the same, we can set the two equations equal to each other and solve for x:
40 + 0.02x = 0.18x
40 = 0.16x
x = 250
So when the customer makes 250 minutes of calls, the cost of the two plans will be the same.
The cost of plan A will be 40 + 0.02250 = $50 and the cost of plan B will be 0.18250 = $45
So when the customer makes 250 minutes of calls, Plan A and Plan B cost the same amount of money.

Why are the values for sine and cosine equal at 45?.
Answer: In an equilateral triangle, the hypotenuse and its opposite side are equal
By the way, I am human. There is too many bot answers.
The values for sine and cosine are equal at 45 degrees because they are related to the right triangle formed by the angle.
In a right triangle, the sine of an angle is equal to the length of the side opposite the angle divided by the length of the hypotenuse. The cosine of an angle is equal to the length of the adjacent side divided by the length of the hypotenuse.
When the angle is 45 degrees, the triangle formed is a 45-45-90 triangle, this is a special triangle in which all the angles are 45 degrees and all the sides are in the ratio of 1:1:√2.
In this triangle, the hypotenuse is √2 times the length of either leg. So, the sine of 45 degrees is opposite/hypotenuse = (1/√2) and the cosine of 45 degrees is adjacent/hypotenuse = (1/√2). Since the opposite and adjacent sides are of the same length in the 45-45-90 triangle, the sine and cosine of 45 degrees are equal.
So, sine 45 = cosine 45 = 1/√2.

Answer:
381 feet
Step-by-step explanation:
You are 220 ft from a tree whose top you see at a 60° angle of elevation. You want to know the height of the tree.
TangentThe tangent relation between sides of a right triangle is ...
Tan = Opposite/Adjacent
where "opposite" and "adjacent" refer to the sides opposite and adjacent to the acute angle of interest.
ApplicationHere, the 60° angle of elevation is adjacent to the 220 ft distance from the tree, and opposite the height of the tree. This means ...
tan(60°) = height/(220 ft)
Multiplying by 220 ft, we find the height to be ...
height = (220 ft)tan(60°) = 220√3 ft ≈ 381 ft
The tree is 381 feet tall.
__
Additional comment
The triangle that models this geometry is a 30°-60°-90° right triangle, one of the "special" right triangles that often shows up in geometry and trigonometry problems. Its side lengths have the ratio 1 : √3 : 2. Knowing this, you know the tree height is √3 times the distance from the tree:
220√3 ft
Your calculator can tell you this is about 381 feet.
To find the height of the tree, we can use the tangent function, which relates the opposite side (the height of the tree) to the adjacent side (the distance from the tree) and the angle. The formula is:
Why is it referred to as a tangent function?
Tangent is derived from the Latin verb tangere, which means "to touch." A circle has one point where a line that is tangent to it intersects.
tangent(angle) = opposite / adjacent
In this case, the angle is 60 degrees, the opposite side is the height of the tree, and the adjacent side is the distance from the tree, which is 220 feet. So we can write:
tan(60) = height / 220
To find the height, we can divide both sides by the tangent of 60 degrees:
height = 220 * tan(60)
The exact value of the height of the tree is not possible to be obtained with the given information, the height of the tree is a number in the infinite set of real numbers.
We can use a calculator or a table of tangents to find an approximate value of the height.
It could be around 379.3 ft.

Therefore, the order in which the terms are multiplied in this order is FOIL (First Outer Inner Last).
An algebraic expression with two terms joined by a plus or minus sign is known as a binomial. Binomial multiplication is comparable to multiplying two whole numbers or fractions. Utilising the distributive property of multiplication twice is one way to multiply binomials.
The letters in the acronym FOIL stand for First, Outer, Inner, and Last. Since only binomials may be multiplied using this approach, it cannot be used to multiply all polynomials. The FOIL formula has the following general form: (a + b) (c + d) = ac + ad + bc + bd.

What is probability ?
Probability is the measure of the likelihood of an event occurring. It is a number between 0 and 1, with 0 indicating that an event is impossible and 1 indicating that an event is certain. Probability can be expressed as a fraction, decimal, or percentage. For example, a probability of 0.5 is the same as a probability of 1/2 or 50%.
The probability of an event can be calculated by counting the number of favorable outcomes and dividing by the total number of possible outcomes.
If 2% of the population has red hair, we can expect 2 out of every 100 people in the population to be redheads. To find out how many redheads we would expect in a sample of 800 people, we can use this proportion and multiply it by the number of people in the sample.

To isolate a, use the log law and rearrange each equation:
[tex]log_a(\frac{3}{2}-h) = 1[/tex]
⇒ [tex]a^1 = (\frac{3}{2}-h)[/tex]
⇒1/a = 3 - h
⇒ a = 1/ [tex]\frac{3}{2}[/tex] - h ....................................(1)
[tex]log_a({3}-h) = -1[/tex]
⇒[tex]a^{-1} = ({3}-h)[/tex]
⇒ 1/a = 3-h
⇒ a = 1/3-h ..............................................(2)
Solve for h:
⇒ 3/2 - h = 1/3-h
⇒ 3-2h/2 = 1/3-h
⇒ 9 - 9h + 2h^2 = 2
⇒(2h-7)(h-1) = 0
⇒ h = 7/2, 1

What is vertex form of a quadratic equation?.
The vertex form of a quadratic equation is written as y = a(x-h)^2 + k, where (h,k) is the vertex of the parabola and a is the leading coefficient.
The vertex form can be converted from the standard form (y = ax^2 + bx + c) by completing the square and shifting the parabola horizontally and vertically.
The vertex form of a quadratic equation is y = a(x-h)^2 + k, where (h,k) is the vertex of the parabola, which is the lowest point for a parabola that opens upwards, and highest point for a parabola that opens downwards. The "a" coefficient is the leading coefficient which represents the direction of the parabola, whether it opens upwards or downwards. The vertex form is useful in identifying the vertex of the parabola and its symmetry axis, as well as its direction.
So, the vertex form of a quadratic equation is written as y = a(x-h)^2 + k, where (h,k) is the vertex of the parabola and a is the leading coefficient.

What quadrant will the point (- 4 2 be located in?.
The point (-4, 2) be located in second quadrant. Due to the fact that x is negative and y is positive.
The coordinate system's two axes, the x-axis and the y-axis, define a region is called a quadrant. The quadrants are generated when the two axes, the x-axis and the y-axis, cross at a 90-degree angle.
These areas include coordinates, or positive and negative values of the x- and y-axes. The position of a point in a quadrant is indicated by the coordinates.
The first quadrant is located in the graph's upper right-hand corner. Both the x and y values in this quadrant are positive.
The second quadrant is located in the graph's upper left corner. The value of y is positive in this quadrant while the value of x is negative.
The third quadrant is located in the graph's lower left-hand corner. It includes both the negative values of x and y.
Fourth Quadrant, the final quadrant has a positive x value and a negative y value, and it is located in the lower right corner.

A perimeter is the length of a two-dimensional shape's boundary. It is sometimes described as the total length of the object's sides. The perimeter of that shape is equal to the algebraic sum of the lengths of its sides.
What is Perimeter?The term "two-dimensional shape" refers to any shape that is flat and has only two dimensions, i.e. length and breadth. Each polygon is a flat, 2-D figure that rests on a plane. Polygons, such as triangles, rectangles, and squares, are closed figures that are enclosed by a series of lines. The length or linear measure of these confined line segments is known as the polygon's perimeter (peri: around; metre: measure). Or to put it another way, it is the length of its borders. The centimetre (cm) or metre is its unit (m).
Perimeter of RectangleThe whole distance that a rectangle's boundaries, or its sides, cover is known as its perimeter. Given that a rectangle has four sides, the perimeter of the rectangle will be equal to the sum of its four sides. Since a rectangle's perimeter is a linear measurement, the unit will be in metres, centimetres, inches, feet, etc.
Perimeter of a rectangle = sum of four sides
= AB + BC + CD + AD
= length + breadth + length + breadth
= 2 length + 2 breadth
Perimeter of a rectangle = 2 × (length + breadth)
Perimeter of CircleThe radius of the circle serves as one of the three variables in the perimeter of a circle formula, along with two constants. The formula for calculating a circle's circumference or perimeter is as follows:
Circumference of a circle is equal to 2πr.
where,
r = radius of the circle
D = diameter of the circle
