Question

In a triangle ABC,angle A=angle B and angle C=50 degree. Find angle A and angle B.

Answer 1

let angle a = angle b = x By angle sum property of a triangle, Angle a + angle b + angle c =180 degree X + x + 50 degree =180 degree   (  angle c =50 degree given ) 2x= 130 degree  X =65 degree Therefore angle a = angle b = 65 degree

Answer 2

Hey Buddy! Here is ur answer ☺
We know that, sim of all angles of a triangle=180°
Let angle A = angle B = x° . Then,
Angle C = 50°
A/q , x + x + 50° = 180°
=> 2x = (180-50)°
=> x = (130/2)°
=> x = 65°.
Hence, Angle A = Angle B = x° = 65°.
