PLEASE HELP!!!!!!
The diagram below models the layout at a carnival where G, R, P, C, B, and E are various locations on the grounds. GRPC is a parallelogram.


Parallelogram GRPC with point B between C and P forming triangle GCB where GC equals 400 ft, CB equals 350 ft, and GB equals 450 ft, point E is outside parallelogram and segments BE and PE form triangle BPE where BP equals 250 ft.


Part A: Identify a pair of similar triangles. (2 points)


Part B: Explain how you know the triangles from Part A are similar. (4 points)


Part C: Find the distance from B to E and from P to E. Show your work. (4 points)
