Question

Help me get the entire process I have to show my work

Answer 1

C. 45

Explanation:

Angles 2 and 3 area pair of adjacent angles on the same straight line

Such angles are called supplementary angles

Their sum is equal to 180°

Therefore
2x + 5 + 85 = 180
2x + 90 = 180

2x = 180 - 90

2x = 90

x = 90/2

x = 45
