This one LZ showed a graph in the original post. It contains two right-angle triangles with a 30 degree angle in each. The two triangles share a side. If you see the graph, you will be able to calculate 5*[3^(1/2)]*[3^(1/2)] = 15

But Lz didn't state that both the left side and right side are perpendicular to the shared side?
