Question

The difference between the exterior angle of a (n-1) sided regular polygon and a (n+1)sided regular polygon is 15 find the value of n .

Answer 1

Answer:

Divide 360 by the difference of the angle and 180 degrees. For the example, 360 divided by 15 equals 24, which is the number of sides of the polygon. Divide 360 by the amount of the exterior angle to also find the number of sides of the polygon.
