Question

Find the angle of one interior angle in this regular polygon, round your answer to the nearest tenth if possible.

Answer 1

144°

Explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 10, thus

sum = 180° × 8 = 1440°

1 interior angle = 1440° ÷ 10 = 144°
