Question

in an isosceles triangle vertex angle is twice of either base angle. find three angle of triangle​

Answer 1

Let, base angle be "b".

So, vertex angle= 2b

Sum of angles in a triangle= 180 degrees

There are 2 base angles and 1 vertex angle.

So,

2b+b+b = 180

4b= 180

b=180/4

b=45 degrees.

Therefore,

b=45 degrees
