Question

If the vertical angle of an isosceles triangle is100 degree then find the measures of its base angles

Answer 1

No Bhai 100 degree nahi ho ga

Answer 2

Base angle of a triangle are equal ,so (angle A) =(angle b)

Sum of all angle of a triangle is =180°

so angle A°+ angle B°+ angle C°=180°

A°+B°+100=180°

Let angle A and B =x

x + x =180°-100°

2x=80°

x =80°/2 =40°

so ,angle A and angle b =40°
