Determine the measure of one interior angle given the sum of interior angles ex 3

The video tutorial explains how to find the measure of an interior angle in a regular polygon. It begins by defining a regular polygon and introduces the formula for calculating the sum of interior angles. The tutorial then demonstrates how to solve for the number of sides in a polygon and use this information to find the measure of one interior angle. The process involves dividing the total sum of angles by the number of sides. The tutorial concludes by summarizing the steps and emphasizing the regularity of the polygon's sides and angles.

If the sum of the interior angles is 1620 degrees, how many sides does the polygon have?

What is the measure of each interior angle in an 11-sided polygon?
