											Answer
C) 40 degrees
Step-by-step explanation:
I would use the inscribed angle theorem as proof. The inscribed angle theorem means that the angle m EFG = x and line EG(80 degrees) = 2x
2x = 80
40 degrees
x = 40 degrees
Answer:
C) 40 degrees
Step-by-step explanation:
The measure of an inscribed angle is 1/2 of the measure of the intercepted arc.
The measure of the arc is 80°. This makes the measure of the angle 1/2(80) = 40°.
