Solve for the missing angle using complementary and supplementary angles

The video tutorial explains how to determine the measures of angles that form a line, making them supplementary and adding up to 180 degrees. It also covers complementary angles, which add up to 90 degrees. The tutorial demonstrates solving for missing angle measures using equations and emphasizes the importance of showing all work to avoid mistakes. The process is summarized with helpful tips for solving angle-related problems.
