Use the sum of interior angles to find the measure of one interior angle ex 2

The video tutorial explains how to find missing measurements in a polygon by using the sum of interior angles formula. It begins by introducing the concept of polygon angles and the relationship between the number of sides and the sum of interior angles. The formula s = (n-2) * 180 is used to calculate the sum of interior angles for a polygon with five sides, resulting in 540 degrees. The tutorial then sets up an equation with variable expressions for the angles and solves for the variable X, ultimately finding that X equals 37 degrees.

What is the formula to calculate the sum of interior angles of a polygon?

• s = n + 180

• s = (n + 2) * 180

• s = (n - 2) * 180

• s = n * 180
