  • Complementary Angles - Angles that add up to 90°

Step-by-step explanation:

Step 1: Set Up Equation

The 2 angles must add up to 90°.

(8m + 4)° + 38° = 90°

Step 2: Solve for m

  1. Combine like terms:                    8m + 42 = 90
  2. Isolate m term:                             8m = 48
  3. Isolate m:                                      m = 6
