Answer:
I believe the answer is 42
Step-by-step explanation:
Given the angle is 138 degrees and we are looking for x
It looks like we are dealing with supplementary angles
Supplementary angles are angles that add up to equal 180.
If this is correct then we would subtract the angle(138) from 180
180-138=42
x=42 degrees
