Question

In an isosceles triangle one of the angle is 120 ° find the other angles

Answer 1

Let the triangle be ABC with AB= AC.

We have, angle BAC = 120 degree.

According to isosceles triangle property, angle ABC is equal to angle ACB since AB = AC.

Let angle ABC= ACB= x.

According to angle sum property of a triangle 120 degree + x + x = 180 degree.

Implies, 120 + 2x = 180

2x = 180-120

2x = 60

x = 60/2

x= 30.

Therefore the other 2 angles are 30 degree.

Answer 2

Answer: the answer is 30
