What is the measure of Angle DEF?

Answer:
D
Step-by-step explanation:
Angles outside a circle are half the difference of the measures of the intercepted arcs.
78 - 12 = 66
66/2 = 33
The angle is 33 degrees
Answer:
The answer is 33 degrees.
Step-by-step explanation: Because the angle is in a circle, we have to divide the answer we get by 2 to get 33. 78-12=66 and divided by 2 is 33.
