Using Same side interior angle find the missing measure of x ex 4

The video tutorial explains how to use the properties of parallel lines and transversals to solve problems involving polygons. It begins by identifying and extending parallel lines and transversals, then moves on to solving angle relationships. The tutorial demonstrates how to calculate angle values using the concept of supplementary angles, specifically focusing on same side interior angles that add up to 180 degrees. The process involves combining like terms and solving for unknown variables.

What steps are involved in solving for the variable X in the equation formed by same side interior angles?

How does the concept of angle relationships apply to the problem presented in the text?
