Question

Is an isosceles triangle the base angle are equal. The vertex angle is 50°.what are the base angles of triangle?

Answer 1

Answer:

the base angles are 65 degree

Step-by-step explanation:

vertex angle = 50degree

base angles are equal

let the angles be x

sum of a triangle is =180degree

x + x + 50 = 180

2x + 50 = 180

x = 180 - 50/ 2

x = 130/2

x = 65

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°
