Answer 2

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

Answer 3

With which formula you have calculated CH?

Answer 4

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

\[CG/6 = EG/(6-DB)\]
