Using the sum of interior angles for a quadralateral to find the measure of each angle

The video tutorial explains how to find the value of X in a polygon by using angle formulas. It covers the sum of interior angles formula and highlights that it only applies to regular polygons. The tutorial then demonstrates calculating the sum of angles for a given polygon, solving for X, and finding the measures of specific angles. The session concludes with a review and addressing any questions.

Calculate the measure of angle Y if X equals 36 degrees.

What is the measure of angle W if it is defined as 3X?
