Question

two conjugate angles are in ratio 5:7.find the angles ​

Answer 1

Step-by-step explanation:

150°, 210°

two conjugate angles are in ratio 5:7

let the angles are 5x,7x

sum of conjugate angles= 360°

5x+7x=360°

12x=360°

x=360°/12

X=30°

5x=5×30°=150°

7x=7×30°=210°

required angles are 150°, 210°
