Question

Two angles  are supplementary and one exceeds the other by 10 degree. Find the angles.

  1. 80, 90
  2. 85, 95
  3. 70 ,80
  4. 75 , 85

The correct answer is: 85, 95


    Let the measure of one angle be x then other angle is x+10.
    As the angles are supplementary
    X+ (x+10)=180
    2x + 10= 180
    2x = 170
    X = 170/2
    X = 85
    Hence, the angles are 85 and 95.
