In your situation I got x = 7.2 inches, CA = 31.2 inches, AD = √(31.2^{2} + 13^{2}) = 33.8 inches and AD = 7.8 inches. The angle t then has measure 138.46 degrees. Draw two semicircles with the same centre and radii 33.8 inches and 7.8 inches. Remove a sector from one end with central angle of 360  138.46 = 41.54 degrees. Good luck with this,
