Question

Two supplementary angles r in the ratio2:3 . Find the angles

Answer 1

Let the angles be '2x' and '3x'.

2x + 3x = 90

5x = 90

x = 90 ÷ 5

Therefore, x = 18

2x = 2 × 18

= 36

3x = 3 × 18

= 54

Thus, the complementary angles are 36 and 54.

Answer 2

angle a=2*x=2x

angle b = 3*x=3x

angle a+angle b=180 degree(supplementary)

= 2x+3x=180

5x=180

180/5

=36

angle a= 2*36=72

angle b= 3*36=108

hope its clear
