What is the measure of an interior angle of a regular 15-gon? A. 135°
B. 54°
C. 156°
D. 24°

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

Bbbhkkk

Ibelieve the answer is c i worked it out three times but if my answer is wrong someone correct me
