Question

in triangle abc if angle A is equals to 5 Angle B and angle C is equals to 3 Angle B find all the three angles of triangle ABC​

Answer 1

Answer:

let angleB be x

angle A= 5x

angle C=3x

sum of all angles =180°

A+B+C=180°

5x + x + 3x =180°

9x=180°

x=180°÷9

x=20°

A=5×20=100°

B=20°

C=3×20°=60°
