Answer:

Step-by-step explanation:
The Pythagorean Theorem says if you have a right triangle, then relationship between the three sides is the sum of the square of each leg is the hypotenuse squared.
So 
where a and b are legs and c is the hypotenuse.
Plug in your a,b, and c. In this case it is a,6, and 8.
This means we have

Simplify where you can before we begin the solving (the moving around of things to other sides).

Now time for the solving. We are first going to get
by itself.
To do this, we just need to subtract 36 on both sides giving us:


Now to get rid of the square on a, just square root both sides:
.
In this item, we are not given with the figure but knowing that these lines ought to be perpendicular then we will be able to derive the relationship between the slopes of the line.
The slopes of the perpendicular line are the negative reciprocals of one another. If we represent the slopes of the lines as m₁ and m₂, the relationship can be written in the form,
(m₁)(m₂) = -1
We are given with one of the slopes. To determine the value of the second slope then,
m₂ = -1/m₁
m₂ = -1/(2/5)
m₂ = -5/2
<em>ANSWER: m₂ = -5/2</em>
14x - 129 (I think I’m so sorry if it’s wrong)
You divide 18 with 3 and is going to equal 6 so that should be your constant proportionality
