What is the measure of the vertex angle of an isosceles triangle if one of its base angle measures 34° and it’s congruent sides each measure 15 cm 68 73 112 56

Let the vertex angle be x.

Base angles in the isosceles triangle are congruent.

Let the base angles be α=34°

Total sum of the inner angles in the triangle is 180°.

We can make equation

2α+x=180° => x=180-2α=180-68=112

The measure of the vertex angle is 112°

Good luck!!!
