how to find the value of x using verticle and supplementary angles

The video tutorial explains how to find the angle of B when given an intersection of two lines and one angle of 130 degrees. It covers two methods: using vertical angles, which are equal, and supplementary angles, which add up to 180 degrees. The tutorial demonstrates how to set up and solve the equation to find the missing angle B, concluding that B is 50 degrees.
