Question

In a ∆ABC, if ∠A = 120°

and AB = A. Find ∠B and ∠C.​

Answer 1

Answer:

$60degree \: each.$

Answer 2

triangle ABC is an isosceles triangle and in a socialist triangle two sides are equal so we can say that angle B equal to angle C as we know that angle A + Angle B + angle c equal to 180 degree by angle sum property of triangle 120 degree + 2 b equals to 180 degrees to be equal to 60 Angle B equal to 60 divided by 2 and the be equal to 30 degree
