How to determine the number of sides of a regular polygon given one interior angle

The video tutorial explains how to calculate the measure of one angle in a regular polygon using the formula (n-2) * 180 / n. It discusses the meaning of variables M and N, where M represents the measure of an angle and N represents the number of sides. The tutorial then demonstrates solving for N when the measure of one angle is given as 120 degrees, resulting in a polygon with six sides. The session concludes with a recap and encouragement for students to note down the solution.

Explain the steps taken to solve for 'N' in the equation derived from the angle measure.

What is the final value of 'N' after solving the equation?
