Given one exterior angle, learn how to find the number of sides of a polygon ex 2

The video tutorial explains how to determine the number of sides of a regular polygon given one exterior angle. It covers the relationship between exterior and interior angles, showing that they are supplementary and add up to 180 degrees. The tutorial then introduces a formula to calculate the number of sides using the interior angle. A step-by-step solution is provided, demonstrating how to solve for the number of sides, resulting in the conclusion that a polygon with an exterior angle of 45 degrees is an octagon.

How do you solve for the number of sides (N) in a regular polygon if the interior angle is known?

What is the number of sides of a polygon if the exterior angle is 45 degrees?
