Question

Find the sum of all interior angles of a regular decagon​

Answer 1

Answer:

The sum of all the interior angles of a decagon is 1440°. There is a formula to find the sum of interior angles of the n-sided polygon [(n-2)(180)] where n is equal to the number of sides. Thus, sum of interior angles of decagon

= (10-2) × 180° = 1440°.
