Triangle Sum Theorem - Part 2 (Solving for X)

This is a more advanced video over the triangle sum theorem. In this video, I'm given a problem where I need to solve each angle measure relative to 'x'. I must solve for 'x' first before I can solve for each angle measure.

The video might take a little while to play. Please be patient.
