Question

each interior angle of a regular polygon is double of its exterior angle find the number of sides in the polygon​

Answer 1

Step-by-step explanation:

Let the exterior angle be x.

Then the interior angle will be double to its exterior angle = 2x.

Then x + 2x = 180

          3x = 180

          x = 60.

Therefore exterior angle = 60.

We know that the size of an exterior angle for a regular polygon = 360/n

 = 360/60

= 6.

Therefore the number of sides in the polygon = 6.
