Thread: Word problems using Geometric formulas

Okay this is a geometry story problem. The story problem reads Roger constructs children's playhouses. At the top of the houses he places an isosceles triangle to form the roof. The largest angle measures 120 degrees. What are the measurements of the other two angles in this triangle?
