Question 1011257
<font face="Times New Roman" size="+2">


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.
