Question

Two angles are complementary. One angle measures 22°. The other angle measures 2x. Determine the value of x.

  1. 55°    
  2. 34°    
  3. 45°    
  4. 75°    

hintHint:

When the sum of two angles is equal to 90 degrees, they are called complementary angles

The correct answer is: 34°


    When the sum of two angles is equal to 90 degrees, they are called complementary angles
    22° + 2x = 90°, 2x = 90° - 22°, 2x = 68°, x = 34°.
