# If ABC is an isosceles triangle and 60°

answer.....

let the angle b and angle c be x as in isosceles triangle 2 sides are equal and other is different

given =

angle a = 60 degree

angle b = x

angle c =x

we know that sum of triangle is 180 degree

so,

60 + x+ x = 180

60 +2x = 180

2x =180 - 60 =110

2x=110

x= 55 degree ans
