hello is there a way to draw a 137.5 by 85 degree angle using only a compass and a straight edge?

Hi Bob - I'm sorry I don't understand your question, is that something you're trying to draw in MoI ?

Yes, I'm trying to construct a Golden angle of 137.5 by 137.5 by 85 degrees approximate in a circle using a compass and a straight edge.Which can be done on a piece of paper.

I recall from math class that the square root of 5 can be so constructed...

According to this link, the answer is YES :-)

But the method is not given...

After reading google links on "Constructible Angles," I'll conclude that construction of 137.5 degrees is NOT possible with compass and straigtedge...
