Question

In an isosceles triangle, the base angles are equal the vertex angle is 50 degree. What are the base angles?

Answer 1

the sum of all angles of a triangle is 180 degree

and the base angles in an isosceles triangle are equal

let the base angle be = x

so

50+x+x=180

2x=180-50

x=130/2

x=65 degree

Answer 2

Answer:

Solution : Let the base angle of triangle = x°

According to question

x + x + 50°= 180°

2x = 180° - 50°

2x = 130°

X = 130°/2

X =65°

Hence the base angle = 65°
