Question

In triangle ABC, AB=Ac and the ratio of A to B is 8 : 5 Find the angles

Answer 1

Answer:

Angle B=50 Angle C=50 Angle A=80

Answer 2

∠A : ∠B = 8 : 5

let ∠A = 8x , ∠B = 5x

Given , AB = AC

∠B = ∠C = 5x ( Isosceles triangle Property)

Sum of Angle = 180

8x +5x +5x =180

18x =180

x = 10°

∠A =8x = 80°
