What exactly is the question I need to answer
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!!!
Answer:
