80 kilometers is equal to 80,000 meters. This is greater than 1000 meters.
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!!!
