What is the measure of each interior angle of a

regular 15-gon?

156

Step-by-step explanation:

1) The formula for finding the sum of interior angles of an n-gon is 180 (n-2)

2) Plug in 15 for n

180 (15-2)

3) Solve

180 (15-2)

180 (13)

2340

4) There are 15 angles in a 15-gon

5) Divide sum of interior angles by number of interior angles

2340/15 = 156

6) So, the answer is 156 degrees
