Question 696427: A base angle if an isosceles triangle measures 50 degrees. Find the number of degrees in the measure of the vertex angle. Answer by Simnepi(216) (Show Source):
You can put this solution on YOUR website! Base angles are equal in an isosceles triangle. so the other base angle is 50 degrees.
Therefore, both base angles total 100 degrees
angles in any triangle add up to 180 degrees.
so the vertex angle is
180 - 100 = 80 degrees.
