Question

What is the missing measure of angle G

Answer 1

You have the correct answer it is 72.

Answer 2

By figure that is a triangle
so ∠f and 122° are supplementary angles
∠f+122=180
∠f=180-122
∠f=  58°
All angles of the triangle add up to 18 degree
so 50+∠g+∠f=180
50+58+∠g=180
∠g=72°
answer is A
