Given an exterior angle determine the missing measure of x

The video tutorial demonstrates two methods to solve for X in a geometric problem involving angles. The first method uses the concept of supplementary angles, while the second employs the exterior angle theorem. Both methods lead to the same solution, showcasing different approaches to reach the same result. The tutorial emphasizes understanding the properties of angles and applying theorems to solve equations effectively.
