In this lesson, we learn how to use the sum of two given angles to find the value of an unknown angle. By adding the two given angles together, we can find the measure of the unknown angle. This concept is then applied to finding the measure of angle ABF, where the values of ABE and EB are given as 2N+7 and 4N-13 respectively. By combining like terms, we can solve for the measure of ABF as 6N-6.

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.
