Question

The ratio between interior angles and the exterior angles of a regular polygon is 2:1 find:
(i) each exterior angle of polygon
(ii) number of sides in the polygon

Answer 1

hiii,

let interior angle be 2x
let exterior angle be x

2x + x = 180
=>3x = 180
=> x = 60
(i) no of exterior angle = 60

(ii) no of sides = 360/60= 6

hope helps
