Understanding Vertical Angles

The video tutorial explains how to solve for an unknown angle x in a geometric figure where two lines intersect at a point, forming vertical angles. The given angles are m = 40 degrees and p = 25 degrees. The tutorial guides the viewer through understanding that vertical angles are equal, leading to the equation x + 25 = 40. By solving this equation, x is found to be 15 degrees. The video emphasizes the properties of vertical angles and demonstrates the step-by-step process of solving for x.
