2. How to Find the Measure of Complimentary Angles Using Algebra
Step 1:
Make sure the angles are complimentary angles.
Step 2:
Setup a solvable equation.
Step 3:
Solve the equation.
Step 1: Complimentary angles are angles that add up to 90º. In this case we know that ∠1 + ∠2 = 90º because we are told they are complementary.
Step 2: Since we know the angles add up to 90º, we can add the two angles and set them equal to 90.
17x x + 9 = 90
26x + 12 = 90
Step 3: Solve the equation.
26x = 78
Step 3: Don't forget the degree symbol.
x = 3
