Given an angle measure solve for the missing variable ex 2

The video tutorial explains the concept of an angle bisector, which divides an angle into two congruent angles. It sets up a problem involving a large angle and its bisected smaller angles, providing their measurements in terms of a variable B. The tutorial then demonstrates how to solve for B by setting up an equation based on the given angle measurements and solving it step-by-step. The final solution shows that B equals 8, illustrating the use of angle bisectors in solving geometric problems.
