- In the given question:
- an angle which is three times of its compliment and less than 20°
- 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
- supplement angle is sum of two angles which is equal to 180° , if two angles add up, to form a straight angle, then those angles are referred to as supplementary angles.
