Question

each interior angle of a regular polygon is double of its exterior angle . find the no. of sides of polygon

Answer 1

Answer:

In a regular polygon each interior is double that of the exterior angle. So if each external angle is x, the adjacent interior angle is 2x. No x+2x = 3x = 180, or x = 60. So the number of sides in the regular polygon is 360/60 = 6.
