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.

Hope this helps!

Answer:

D

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
