The figure shows the intersecting circles O
and O' at A and B. The diameter AC of circle O meets circle O' at E, the
diameter AD of circle O' meets circle O at F. Line DE meets circle O at
G,H, line CF meets circle O' at M,N. If the measure of angle CAD = 58 degrees and the measure
of angle CNH = 22 degrees, find the measure of angle FMG.
