Question

Identify the pair of supplementary angles.

  1. x°, 180° - x    
  2. x°, 180° + x    
  3. x°, 180° × x    
  4. x°, 180° ÷ x    

hintHint:

x°+180° - x = 180°

The correct answer is: x°, 180° - x


    Supplementary angles refer to the pair of angles that always sum up to 180°. These two angles are
    called supplements of each other.
    here, the pair of the supplementary angles are x°, 180° - x 
    x°+180° - x = 180°
