In rectangle EFGH, EH=3 and EF=4. Let M be the midpoint of EF, and let X be a point such that MH=MX and angle MHX=72, as shown below. Find angle XGH, in degrees. Thank you! By the way, I don't know how to do this problem but I reccommend using circles and the properties of the angles inside them.
Here is the image:
