Using complementary angles to find the missing value

The video tutorial explains how to determine the measures of angles formed by intersecting lines. It highlights that if one angle is a right angle, all angles are 90 degrees, indicating perpendicular lines. The tutorial then guides viewers on solving for unknown angles by setting up equations, emphasizing the importance of assigning variables and solving systematically.

What is the relationship between the measures of angle four and angle five in this context?

How do you determine the measure of angle five after knowing the measure of angle four?
