Question

Prove that all the exterior angles of a regular pentagon add up to 360

Answer 1

Step-by-step explanation:

Each angle =(n-2)180/n

Each angle of regular pentagon=(5-2)180/5=108°

Since the sum of exterior all exterior angles of a polygon=360°

Therefore each exterior angle of decagon=360/8

=36°

3*36=108°

Hence proved
