Given a polygon, solve for x and all of the interior angles using sum of interior angles

The video tutorial explains how to solve a geometry problem involving a hexagon. It begins by identifying the problem and variables, then explains the properties of a hexagon. The tutorial demonstrates how to calculate the sum of interior angles and solve for the variable X. Finally, it shows how to find the measures of individual angles using the calculated value of X.

What is the measure of angle B if it is defined as X - 8 and X is 120 degrees?

List the measures of angles C, D, E, and F based on the value of X being 120 degrees.
