Answer 2

Step-by-step explanation:

Step-by-step explanation:In an isosceles triangle ABC,

AB=AC

AB=ACBase angles are equal

AB=ACBase angles are equalLet ∠B=∠C=x

∠A= x/2

∴ x+x+ x/2=180°

2x+2x+x/2=180°

5x/2= 180°

5x=180°*2

5x=360°

x=360°/5

x=72°

∴ ∠B=∠C=72°

Vertical angle=x/2 =72°/2=36°

Angles of the triangles will be 72°,72°,36°
