Question

Find the measure of one of the exterior angle of a refular decagon

Answer 1

Answer:

36°

Step-by-step explanation:

Sum of all interior angles of regular decagon= (n-2) ×180

= 1440°

Each interior angle= 1440/10 = 144°

As we know that the sum of interior and exterior angles is 180°

Interior angle + Exterior angle = 180°

Exterior angle = 180-144

= 36°
