Using Equations to Solve for Unknown Angles

Open Up Resources 35 min(s)Support for English Language Learners

In the previous lesson, students saw that equations could be used to represent relationships between angles. In this lesson, students practice writing and solving equations of the form in the context of finding unknown angle measures. This brings together their work with equations from the previous unit and their work with angles from earlier lessons in this unit, giving students a chance to build fluency with both of these concepts. Use a variable to represent the measure of an angle and an equation to represent a relationship between angle measures.
