Problems with angles are done on this video.
• How do you solve for a variable in angle problems?
• If x and x + 30 are complementary, what does x equal and what are the measures of the angles?
• If x and 4x + 10 are complementary, what does x equal and what are the measures of the angles?
• If 2x, x + 25, and x - 5 are supplementary angles, what is each angle measure?
• If an angle is 15 degrees more than twice its supplement, what is the measure of the angle?
This lesson shows four different problems involving angle measures and variables. Properties of angles are used to set up and solve equations to find the variable, and then the angle measures are found. All steps are shown and explained in each problem.
