Question

Find the measure of sum of the interior angle and each of the interior angle of a decagon.​

Answer 1

Answer:

Each Interior Angle = 144°

Sum of all interior angles = 1440°

Step-by-step explanation:

Sum of all interior angles of decagon = (n - 2) x 180°

(where n is number of sides)

(10 - 2) x 180°

8 x 180° = 1440°

Each interior angle = 1440/10 = 144°
