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.
