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

Answer:
144°
Step-by-step 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°
