Question 1011257: An isosceles triangle has a base angle of 30 degrees. Find the vertical angle.
If possible, please explain this question with a diagram. If possible! Thanks! Answer by solver91311(24713) (Show Source):
If one of the base angles of an isosceles triangle is 30 degrees, then the other base angle is 30 degrees as well; that's what makes it an isosceles triangle. Then knowing that the sum of the interior angles of any triangle is 180 degrees makes determination of the vertex angle a simple subtraction problem.

My calculator said it, I believe it, that settles it
