Part of video series Solving for Angle Measures
Taught by mrbrianmclogan
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.
In this lesson, I show how to solve for x and y in angle measure expressions within a quadrilateral.
  • How do you find the measures of the angles in a quadrilateral?
  • What angle measure do all of the angles in a quadrilateral add to?
  • If four angle measures in a quadrilateral are 96, 94, 2x, and 3y + 44, what do x and y equal?
  • What two angle measures add up to 180 degrees in a trapezoid?
  • Why do two angles in a trapezoid add up to 180 degrees?
  • If 94 + 3y + 44 = 180, what does y equal?
  • If 96 + 2x = 180, what does x equal?
This video does a good job of explaining how to figure out angle measures in a trapezoid. There is a small mistake that is corrected in the lesson where an equation is solved to find one of the angle measures. All steps in the process of finding the angle measures are explained.
