Question

In a regular polygon each interior angle is 140° greater to each exterior angle. Calculate the number of sides of the polygon.​

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.
