Answer:
x = -14
Step-by-step explanation:
The two marked angles are called vertical angles and they are EQUAL to each other. Write an equation:
9x + 184 = 7x + 156
subtract 7x from both sides.
2x + 184 = 156
subtract 184 from both sides.
2x = -28
divide by 2.
x = -14
to find the measure of the angles, substitute in -14 for x. They both come out to be 58°.
