Lesson Summary:

In this lesson, the concept of modeling an angle with an equation is explored. The instructor provides a simple example using numbers and then progresses to using expressions. By subtracting the part from the whole, students can find missing values of angles. The lesson explains the process of finding the measure of angle ABF by using an equation and combining like terms. This technique will help students model a part or a whole of an angle with ease.

Lesson Description:

Using an equation to model part and whole of an angle

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.

Questions answered by this video:
  • If I am given the measure of a whole angle and the measure of a part of the whole angle, then how do I find the measure of the other part of the whole angle?
  • Angle ABE and angle EBF together form angle ABF. The measure of angle ABF is 8x-6, and the measure of angle ABE is 2(x+11). How do I find the measure of angle EBF?

    The problem in this lesson has angles ABE and EBF that make up angle ABF. It gives the measures of angles ABF and ABE in terms of a variable x, and the lesson shows how to find the measure of angle EBF.
