Okay, 72 degrees is equal to (5x-98), so
72=5x-98
5x=170
x=34

So now that we know that x=34, we can put 34 into (5x-98), so 170-98
170-98 and y are supplementary, so they add up to 180 degrees. So the equation is 
170-98+y=180
72+y=180
y=180-72
y=108

I need help please I need it
SashulF [63]

Step-by-step explanation:

It asks you to choose values for w, the width, and evaluate the equation for each. It describes the constraint "the perimeter of 20 units" The perimeter of a rectangle is the length of all the lines of a regtangle.

Or

2L + 2W = 20 reduce this to simplest for by dividing both sides by 2;

L + W = 10, so the length plus the width is 10. Rearrange it to be W = 10 - L. Values of W can range from 1 to 9. Now sove for a few points in the function.

f(W) = 10W - W^2

3; 10(3) - 3^2 = 30 - 9 = 21.

If we look at the constraint, L = 10 - W, when the width is 3 the length must be 7. The area of a rectangle is L x W, 3 x 7 = 21. That checks against the function.

Solve for additional points.

4; 10(4) - 4^2 = 40 - 16 = 24.

If W is 4 the L is 6 and 4 x 6 = 24
