Use the sum of exterior angles to solve for the missing variable ex 3

The video tutorial explains how to solve for a missing variable when given exterior angles instead of interior angles. It highlights that the sum of exterior angles is always 360 degrees, regardless of the number of sides. The instructor demonstrates setting up a large equation, combining like terms, and solving it step-by-step to find the missing measure. The process emphasizes careful calculation to avoid mistakes.
