Find the measure of each exterior angle of a regular polygon of(i) 9 sides (ii) 15 sides

Answer» Sum of all exterior angles of a regular polyfon is `360^@`.
If `n` is number of sides and `x` is its exterior angle. Then,
`nx = 360^@`
(i) Here, `n = 9`
So, Exterior angle, `x = 360/9 = 40^@`

(ii) Here, `n = 15`
So, Exterior angle, `x = 360/15 = 24^@`
