Problem Statement

Rectangles ABCDABCD and EFGHEFGH are drawn such that D,E,C,FD,E,C,F are collinear. Also, A,D,H,GA,D,H,G all lie on a circle. If BC=16,BC=16, AB=107,AB=107, FG=17,FG=17, and EF=184,EF=184, what is the length of CECE? [asy] unitsize(1 cm);
pair A, B, C, D, E, F, G, H;
A = (0,0); B = (5,0); C = (5,1.5); D = (0,1.5); E = (1,1.5); F = (8,1.5); G = (8,3.5); H = (1,3.5);
draw(A--B--C--D--cycle); draw(E--F--G--H--cycle);
dot("A", A, SW); dot("B", B, SE); dot("C", C, SE); dot("D", D, NW); dot("E", E, NW); dot("F", F, SE); dot("G", G, NE); dot("H", H, NW);
