Question

: Calculate the sum of the interior angles of a 13-sided polygon.​

Answer 1

Answer:

The sum of the exterior angles of a 13-sided regular or irregular polygon is 360 deg. The sum of the interior angles of a 13-sided regular or irregular polygon = (2n-4)*90 = 22*90 = 1980 deg. Each interior angle of a 13-sided regular polygon only = 152.3076923

Explanation:

Answer 2

Answer:

Explanation:

The formula for the total sum of the interior angles of a regular polygon is

(number of sides - 2)*180

In this case, there are 13 sides.

(13 - 2) * 180 =

11 * 180

1980
