Question

PLEASE SOMEONE HELP ME ILL MARK BRAINLESS AND PLEASE EXPLAIN AHHHH HELP

Answer 1

Answer:  100 degrees

===============================================================

Explanation:

The two angles that involve x are alternate interior angles.

Due to the parallel lines, the alternate interior angles are equal.

We'll use this to solve for x

-7x-18 = -9x-46

-7x+9x = -46+18

2x = -28

x = -28/2

x = -14

Let's check the answer by evaluating each expression as shown below

• -7x-18 = -7*(-14)-18 = 80
• -9x-46 = -9*(-14)-46 = 80

Both angles are 80 degrees each, so it confirms we have the correct x value.

-----------------------

We have one last step. We found the -9x-46 angle to be 80 degrees. Angle 4 is adjacent to this and supplementary.

So we subtract from 180 to get the answer

180-80 = 100
