Find the measure of x given interior angles of a pentagon

The video tutorial explains how to calculate the sum of interior angles of a polygon using the formula (n-2) * 180 degrees, where n is the number of sides. The instructor demonstrates the process by determining the number of sides, calculating the sum of angles, and solving for X using algebraic expressions. The tutorial emphasizes combining like terms and solving equations to find the value of X, which represents the measure of each angle in the polygon.
