Learn how to determine the missing value using the exterior angles of a polygon ex

The video tutorial explains how to determine missing measures of exterior angles in polygons. It emphasizes that the sum of exterior angles in any polygon is always 360 degrees, regardless of the number of sides. The instructor demonstrates setting up and solving an equation to find the value of unknown angles, using a specific example. The process involves adding known angles, setting up an equation, and solving for the unknown variable. The tutorial concludes with verifying the solution.
