At the end of the lesson, the final answer should be y = 26 1/3 OR 26.33333..., NOT 26.2

Lesson Summary:

In this lesson, we learn how to use angle measures and relationships to solve for variables. The instructor shows how to use vertical angles and supplementary angles to solve for X and Y in an example problem. Through the process, we see how different angle relationships, such as alternate interior angles and corresponding angles, are used to find the values of unknown angles.

Lesson Description:

Solving for a variable in angle measure relationships. Vertical angles and supplementary angles are used in this example.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
