Question 1203796
<pre>
This problem is botched. The figure below is drawn to scale.
As you can look and readily see, if GC=2 cm, BG must be a lot longer than 4 cm.
In fact, BG would have to be 7.4641015 cm.  So there is no use trying to
get an answer to this problem.  If you give me corrected numbers, I'll help you.
