Answer its rhombus
Step-by-step explanation: i took the test
The quadrilateral formed by the taping together of two equilateral
triangles is a rhombus.
How can the type of quadrilateral formed be known?The given types of triangles that form the quadrilateral are equilateral
triangles.
Given that the triangles have congruent side lengths, we have;
1) The side lengths of the quadrilateral formed are equal.
2) A pair opposite angles of the quadrilateral formed are equal to the interior angle of an equilateral triangle which is 60°.
3) The other pair of opposite angles are also equal to 60° + 60° = 120°.
The altitude of an equilateral triangle is perpendicular to the base.
Which gives;
4) The diagonals bisect each other at right angles.
Therefore;
The adjacent angles are supplementary
Which gives;
5) The opposite sides are parallel.
The above properties are the properties of a rhombus
Therefore;

a) Solve 3(x - 5) = 18
4(x - 2) + 3 = 2x - 9
The value of x from the given equation is -2.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 4(x - 2) + 3 = 2x - 9.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
4x-8+3=2x-9
4x-5=2x-9
4x-2x=-9+5
2x=-4
x=-2
Therefore, the value of x from the given equation is -2.

i need someone to solve for the variable and show how plzz
Answer:
Step-by-step explanation:
2(x + 15)⁰ + (3x + 20)⁰=180⁰
2x + 30⁰ + 3x + 20⁰=180⁰
2x + 3x + 30⁰ + 20⁰=180⁰
5x + 50⁰ - 50⁰=180⁰-50⁰
5x=130⁰
5x/5=130⁰/5
x=26⁰
Answer:
x should equal 26.
Step-by-step explanation:
since they are cointerior angles:
2 (x + 15) + (3x + 20) = 180
2 (x) + 2 (15) + (3x + 20) = 180
2x + 30 + (3x + 20) = 180
2x + 30 + 3x + 20 = 180
5x + 50 = 180
5x + 50 - 50 = 180 - 50
5x = 130
5 ÷ 5x = 130 ÷ 5
x = 26

A shooting star forms a right triangle with the Earth and the Sun, as shown below: A right triangle is shown with the vertices labeled Earth, Sun, and Shooting Star. The angle formed by the Sun is labeled x deg A scientist measures the angle x and the distance y between the Earth and the shooting star. Which trig function would the scientist use to calculate the distance between the Earth and the Sun. (5 points) sin cos tan sin-1 cos-1 tan-1
Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene triangle, obtuse triangle, equilateral triangle and right angled triangle.
Trigonometric functions are functions used to show the relationship between an angle of a right-angled triangle and the ratio of two side lengths. Below are some trigonometric function:
sinθ = opposite/hypotenuse, cosθ = adjacent/hypotenuse, tanθ = opposite/adjacent.
Given the right angled triangle with angle x. and the hypotenuse y. We need to find the distance between the Earth and the shooting star.
d = distance between the Earth and the shooting star = adjacent side.
Therefore, the relationship between angle x, d and y can be gotten using the cos trig function.
cosθ = adjacent / hypotenuse
cos(x) = d / y
d = y * cos(x)

Answer:
Use Pythagorean Theorem to find the distance between the two points
[tex]x^{2} +y^{2} =r^{2}[/tex] where r is the distance between the two points
Δx = 6-4 = 2
Δy = 3-(-1) = 4
2²+4²=r²
4+16=r²
20=r²
√20=r
r=4.47
r=4.5

∴The distance between the cafeteria and the bathrooms is 2.25 units
Hopefully you understand how I got this answer.
Answer:
(5,1)
Step-by-step explanation:
So for this one we just find the length between the x values and the length between the y values and divide by 2 to find how far it will be ( if that makes sense.)
the distance between the two x values is 2 and the distance between the two y values is 4
2/2 = 1 and 4/2 = 2
then we subtract 1 from the x value and 2 from the y value ( using the coordinates of the cafeteria btw.)
6-1=5 and 3-2 =1 so the coordinates of the bathroom is (5,1)
Mr. Reed is drawing a blueprint of a rectangular patio. The width of the patio is 40 3/4 feet shorter than twice its length. The perimeter of the patio 86 1/2 feet what is the length of the patio?
Answer:
Length of rectangular patio = 28 feet
Step-by-step explanation:
Given that:
Length of rectangular patio = x
Width of rectangular patio = [tex]2x-40\frac{3}{4}[/tex]
Perimeter of rectangular patio = [tex]86\frac{1}{2}[/tex]
Perimeter of rectangular patio = 2 (length + width )
Putting values in the formula
[tex]86\frac{1}{2}=2(x+2x-40\frac{3}{4})\\\\\frac{173}{2}=2(3x-\frac{163}{4})\\\\\frac{173}{2}=2(\frac{12x-163}{4})\\\\\frac{173}{2}=\frac{12x-163}{2}\\\\173 = 12x-163\\12x = 173 + 163 \\12x = 336[/tex]
Dividing both sides by 12
[tex]\frac{12x}{12}=\frac{336}{12}\\x=28[/tex]
Hence,
Length of rectangular patio = 28 feet

your maximum "point" of the polynomial is the highest point that the curve makes which in this case is around x=-3.6 and y=17
The point of maxima for the given function is (-3.6, 17).
What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
As per the graph of the function following conclusion are as below,
It has a maxima in second quadrant.
After the point of maxima, its value starts to decrease.
Then, it reaches it lowest value in fourth quadrant after which it increases again.
By examining the given options, the correct point of maxima can be found as (-3.6, 17).
Hence, the point of relative maxima for the graph can be evaluated as (-3.6, 17).
