Question

The ratio between the interior angle and
the exterior angle of a regular polygon is
2: 1. Find :
(1) each exterior angle of the polygon,
(ii) number of sides in the polygon.​

Answer 1

Answer:

Step-by-step explanation:

Interior angle=2x,

Exterior angle=x,

x+2x=180,

3x=180,

x=180/3,

x=60,

Let the number of side=n,

Sum of exterior angle = 360°,

60n=360,

n=6,

So there are 6 sides.
