Answer 1

1a) Some of the interior angles of a 15-gon must be 13 x 180=2340 degrees. Since it’s regular, the total is shared equally among the interior angles. 2340/15=156 degrees

Answer 2

Answer:

1a) 2340

1b) 120°

Step-by-step explanation:

1a) formula to find the sum of the interior angles is: (n-2) * 180

n = the number of sides

(15-2) * 180

(13) * 180 = 2340

2a) the formula to find the measure of one interior angle is:   $\frac{(n-2) * 180}{n}$

n = the number of sides

a hexagon has 6 sides

(6-2)*180

4 * 180 = 720

720 ÷ 6 = 120
