Let exterior angle (e)=x∘
∴ Interior angle (i)=2x∘
i+e=180∘
2x+x=180∘
3x=180∘
x=60∘
∴e=60∘
n=360e

If the interior angle of a regular polygon is double the exterior angle, then the polygon has ______ sides.
The exterior angle of a regular polygon is one – third of its interior angle. How many sides has the polygon?
Each interior angle of a regular polygon is 144°. The measure of each interior angle of a regular polygon which has double the number of sides as the first polygon is
