Find the number of degree in each exterior angle of a regular pentagon.

Text Solution

Verified by Experts

A regular pentagon has `5` sides.
Each exterior angle of a polygon`=360^@/n`, where `n` is number of sides.
Each exterior angle of a polygon`=360^@/5=72^@`
Hence, the number of degree in each exterior angle of a regular pentagon is `72^@`.
