Angle Relationships and Measurements

This lesson focuses on solving for unknown angles using equations. It covers several examples, including solving for angles T, V, X, AOB, and BOC by applying concepts of vertical and adjacent angles. Each example involves setting up and solving equations to find the unknown angles, reinforcing the understanding of angle relationships and equation solving techniques.
