  • based on this statement , the equation formed
  • 3x-20° = 180° (
  • sum of supplement)
  • 3x =180-20
  • 3x= 160
  • x=53.3
  • complement angle is a sum of two angles which is equal to 90° , if two angles add up to form a right angle, then these angles are referred to as complementary angles
