Question

three angle are supplymentry one angle is 40 and other angle are x and y . X and Y are in ratio 2:3 .find the angle .​

Answer 1

Answer:

if the angles are supplementary their total shall be 180

so angle A = 40

angle B = 2x

angle C = 3x

A + B + C = 180

40 + 2x + 3x = 180

5x = 140

x = 28

angle b = 2 × 28 = 56

angle c = 3 ×28 = 84

Answer 2

let the measure of angle x and y is m

2m+3m+40°=180°

5m+40°=180°

5m=180°-40°

5m=140°

m=140°÷5

m=28°

x=2m

x= 2*28

x=56°

y=3m

y=3*28

y=84°
