I found CH. Where should i take moment to find EG and FG

With which formula you have calculated CH?

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 $CG/6 = EG/(6-DB)$
