Question

one of the base angles of an isosceles triangle is 52 degree. find its angle of vertex​

Answer 1

We know,

That in isosceles triangle, base angles are equal...

So,

In triangle ABC,

A+B+C=180°[Sum of angles of triangle is equal to 180°]

Or,52°+52°+C=180°

OR,104°+C=180°

C=76°

Hence angle of vertex=76°
