Question

Find the sum of the measures of the interior angles of a
polygon with 10 sides.​

Answer 1

1440

Explanation:

The sum of the exterior angles of a regular polygon of 10 sides = 360 deg. The sum of the interior angles of a regular polygon of 10 sides = 10*[180 - (360/10)] = 10(180–36) = 10*144 = 1440 deg.
