Using adjacent angles, The value of a given figure, the value of E = 132°

What is an Adjacent angle?

When two angles have a similar vertex and side, they are referred to as neighboring angles. The vertex of an angle is the point at which the rays that make up its sides come to an end. When adjacent angles have a same vertex and side, they can be a complimentary angle or supplemental angle.

draw a line EOF parallel to AB

now EF || AB and CD||AB

∵ AB || EF and AO is a transversal

we have

∠AOF+∠OAB=180°

∠AOF+108 = 180 °

∠AOF=72 °

∵ EF|| CD and OC is transversal

so

∠COF+∠OCD=180°

∠COF+112° = 180°

∠COF=60°

∴∠AOC=∠AOF+∠COF

=72 ° + 60°

=132°

Answer:

Question 4 : 10 m

Question 5 : Square root 37

Step-by-step explanation:

QUESTION 4: So for the this one here we need to make a drawing (unfortunately). Lets break down the question because having a math problem with a ton of words is confusing sometimes. So we have a pole that is 8m high, so we can draw that out. So we take some cable and go 6 m from the bottom of the pole. So now we want to know how long the cable is and if we go from the top of the pole to the bottom 6m away it looks like this. (Below I'll put what I have written) Since now it's a 90 degrees angle there is a specific formula we can use in situations like this. Where we know 2 sides and need 1 more. a^2 + b^2 = c^2 should look familiar if it doesn't its all good! :D a^2 + b^2 = c^2 is called 'Pythagorean's theorem' (we don't really need to know that part) but basically we use it whenever we need to figure out a side when we already know the other two. We know that the straight line is 8, and the horizontal line is 6. So we can use that formula to get the last number. just know that whenever we have the right triangle, we can use the a^2 + b^2 = c^2 to get all the sides for it. The a and b in the formula are always the straight lines. The c is always the slanted line (the red line I drew). We don't know what it is, so we'll just put c^2 into our equation but we can solve for it! So 8^2 would equal to 64. 6^2 would equal to 36. 64 + 36 here gets us 100. Here's another trick you might need to memorize. Whenever there is a number squared like c^2, we can take the square root of both sides to get rid of it. So c^2 just becomes c. It's a little weird but very useful to remember.  But if you remember the a^2 + b^2 = c^2 and use that square root technique you can get an A+ every time. :D Now all we need to know is the square root of 100. It's a big one so using a calculator is fine, here its just 10. Therefore our answer is 10.

QUESTION 5:  We'll start off by reading 'distance between points' is a big thing to note here. There is a formula that we can directly use here. (I'll write under the picture in black). So distance between points always uses this formula: (In black). Okay, so the formula in black has more letters in it (which sucks) but we can break it down. When we have numbers like this (3, 0) it means (x, y). So I wrote down what the x1, y1, x2, y2, are here. X1 is just the first number, y1 is the second, x2 is the third, and y2 is the fourth. I just plugged in all the numbers from above in the order we put (x2, x1, y2, y1). Basically we can just solve this now! As of right now we'll need to solve (-3 -3)^2 when we solve that we should get 36. Next we're gonna solve  (-1 - 0)^2 and we should get the answer of 1. Now we need to solve 36 +1 and we should know that it equals 37. Therefore we'd get answer: square root 37.

The inequality can be simplified to:

x > -1

And the graph can be seen in the image below.

Here we have the inequality:

5x + 8 > 3

To solve this, we need to isolate the variable x in one side of the inequality.

5x + 8 > 3

We subtract 8 in both sides:

5x > 3 - 8

5x > -5

Now we divide both sides of the inequality by 5.

The distance between the pair of parallel lines given by the equations y = -4x - 6 and y = -4x + 11 is √17 units.

The shortest distance between two parallel lines is the length of the perpendicular segment between them.

First, determine the slope of the segment perpendicular to the parallel lines.

y = -4x - 6

m = -4

slope of perpendicular segment = 1/4

Consider a point that one of the equation passes through. Line y = -4x - 6 passes through (0 , -6).

Write the equation for the perpendicular line using the point-slope form.

(y - y1) = m(x - x1)

(y - -6) = 1/4(x - 0)

y + 6 = 1/4 x

y = 1/4x - 6

Determine the point where this perpendicular line intersects with the 2nd parallel line by equating both equations.

y = 1/4x - 6 = -4x + 11

1/4x + 4x = 11 + 6

17/4 x = 17

x = 4

Substitute this value of x in the previous equations,

y = 1/4x - 6

y = 1/4(4) - 6

y = 1 - 6

y = -5

Now, the distance between the two points (0 , -6) and (4 , -5) is the distance between the two parallel lines.

d = √(x2 - x1)^2 + (y2 - y1)^2

d = √(4 - 0)^2 + (-5 - -6)^2

The equation of the line 5y = -3x - 10 expressed in slope-intercept form is y = -3/5 x - 2 with a slope equal to -3/5.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The slope-intercept form of the equation of a line is given by the formula:

y = mx + b

where m is the slope of the line

b is the y- intercept

Given the equation of the line 5y = -3x - 10, which the variable y is already isolated in one side, divide both sides by 5.

The two consecutive integer numbers are 24 and 25.

We can write the two consecutive integers as x and x + 1, where the larger one is x + 1.

We know that 1/5 of the larger is 7 less than 1/2 of the lesser one, then we can write the linear equation:

1/5*(x + 1) = 1/2*x - 7

1/5*x + 1/5 = 1/2*x - 7

So we need to solve that for x:

1/5 + 7 = 1/2*x - 1/5*x

1/5 + 35/5 = 5/10*x - 2/10*x

36/5 = 3/10*x

(36/5)*(10/3) = x = 24

Inequality:

In mathematics, a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions. Inequalities can be posed either as questions, much like equations, and solved by similar techniques, or as statements of fact in the form of theorems. For example, triangle inequality states that the sum of the lengths of any two sides of a triangle is greater than or equal to the length of the remaining side. The mathematical analysis relies on many such inequalities (e.g., the Cauchy-Schwarz inequality) in the proofs of its most important theorems.

In mathematics, an inequality is a relation that makes a non-equal comparison between two numbers or other mathematical expressions.[1] It is used most often to compare two numbers on the number line by their size. There are several different notations used to represent different kinds of inequalities:

The notation a < b means that a is less than b.

The notation a > b means that a is greater than b.

In either case, a is not equal to b. These relations are known as strict inequalities,[1] meaning that a is strictly less than or strictly greater than b. Equivalence is excluded.

In contrast to strict inequalities, there are two types of inequality relations that are not strict:

The notation a ≤ b or a ⩽ b means that a is less than or equal to b (or, equivalently, at most b, or not greater than b).

The notation a ≥ b or a ⩾ b means that a is greater than or equal to b (or, equivalently, at least b, or not less than b).

The relation not greater than can also be represented by a ≯ b, the symbol for "greater than" bisected by a slash, "not". The same is true for not less than and a ≮ b.

The notation a ≠ b means that a is not equal to b; this inequation sometimes is considered a form of strict inequality.[2] It does not say that one is greater than the other; it does not even require a and b to be member of an ordered set.

In engineering sciences, less formal use of the notation is to state that one quantity is "much greater" than another,[3] normally by several orders of magnitude.

The notation a ≪ b means that a is much less than b.[4]

The notation a ≫ b means that a is much greater than b.[5]

This implies that the lesser value can be neglected with little effect on the accuracy of an approximation (such as the case of ultra relativistic limit in physics).

In all of the cases above, any two symbols mirroring each other are symmetrical; a < b and b > a are equivalent, etc.

The orthocenter is the point where a triangle's three altitudes intersect, and the centroid is the point where the three medians intersect.

The coordinates of the orthocenter of Δ RST is (3, 6).

An orthocenter of a triangle is the point at which altitudes drawn perpendicular from the vertex to the opposite sides of a triangle intersect. A triangle typically has three altitudes, and the intersection of all three altitudes is known as the orthocenter.

The orthocenter is the point where a triangle's three altitudes intersect, and the centroid is the point where the three medians intersect.

The midpoint of AD is (-1+3/2, 11+1/2) or (1, 6). Note that DC is a line that connects the vertex C and D, the midpoint of AB. The distance from D(1, 6) to C(7, 6) is 7 - 1 or 6 units.

If P is the centroid of the triangle XYZ, then PC = (2/3) DC.
