Question

find the measure of each interior angle of a regular 20 sided polygon​

Answer 1

Step-by-step explanation:

Each exterior angle of a regular polygon of 20 sides = 360/20 = 18 deg.

Each interior angle of a regular polygon of 20 sides = 180 - 18 = 162 deg.

Total sum of the 20 interior angles of the regular polygon = 162 × 20 = 3240 deg.
