Angle Equations
MCC7.G.5 Use facts about supplementary, complementary, vertical, and adjacent angles in a multi‐step problem to
write and solve simple equations for an unknown angle in a figure.
For each problem, write an equation to find the value of x then solve it.

9. When a basketball hits a hard, level surface, it
bounces off at the same angle at which it hits. Use the
figure to find the angle at which the ball hit the floor.
10. <A and <B are complementary angles. The measure of <B is (4x)°, and the measure of <A is
50°. What is the value of x?
11. Angles E and F are supplementary. If m<E = x – 10 and m<F = x + 2, find the measure of
each angle.
