Question

in a supplement angle the numbers are in ratio 2:3 . what are these two angles​

Answer 1

Answer:

supplement means total angle will be x

now the two angles are in ratio 2x and 3x

2x + 3x = 180

5x = 180

x = 36

so the two angles are 72° and 108°

Answer 2

Let the unknown angles be 2x and 3x.

Sum of supplementary angles=180

i.e 2x + 3x = 180 °

5x = 180 °

Therefore, x = 180°÷ 5

= 36°

So first angle = 2x = 2×36= 72°

Second angle=3x = 3×36= 108°
