    Length of FG. Calcute first AG, \[\sqrt{(11^{2}+6^{2})} \] Now you can see that AGC and FG(put some middle point O) are two similar right triangle so you can find FG: \[AG/11 = FG/5\] Length of EG You can see that CGH is similar to EG(put some point Z). Now you need to find new h of the EGZ. h(ofRGZ) is 6-DB. DB is similar to the AGO (first triangle). \[AD/6 = AG/11\] \[DB = \sqrt{ AD ^{2}+AB ^{2)}}\] Now you get DB 6-DB ---> new h of RGZ \[CG/6 = EG/(6-DB)\]
