Complementary and Supplementary Angles Concepts

This video tutorial teaches how to solve equations involving complementary and supplementary angles. It provides step-by-step instructions for solving for variables in angle equations, demonstrating with examples. The video covers setting up equations, combining like terms, and using inverse operations to find the values of variables. It also explains how to calculate the measures of individual angles once the variable is known, ensuring the sum matches the expected angle total.

What is the sum of complementary angles?

• 180 degrees

• 45 degrees

• 90 degrees

• 360 degrees

In the first example, what is the equation set up for complementary angles?
