recall that the sum of the angles of any triangle is 180°
You already have two of them, so getting the third should be no trouble, yeah?

The Transamerica Pyramid building shown in the photograph has four faces shaped like isosceles triangles. The measure of a base angle of one of these triangles is about 85 degrees. What is the approximate measure of the vertex angle of the triangle?
