Question

The ratio of an exterior
angle to an interior
angle of a regular polygon is 1
:
3
. Find the number of sides of the polygon.

Answer 1

Answer:

111:1243 is the ratio okkkkkk

Answer 2

Step-by-step explanation:

let the interior angle be x,

the exterior angle be x/3

Exterior angle +Interior angle =180

x/3+x=180

4x/3=180

4x=180×3

x=180×3/4

x=135

Exterior angle =135/3

Exterior angle =45

n=360/45

n=8

no.of sides =8
