I know the 65 degrees refers to the angle, but is the 45' a further incrementation of a degree, and if so, how is it calculated? What would the decimal value be?
This is from an architectural drawing from the 1930's.
Thanks in advance.

"is the 45' a further incrementation of a degree...?"
Yes. It indicates arcminutes. One arcminute is 1/60 of one degree.

Called minutes, often accompanied by even smaller declination; seconds
If you use autocad, you can enter angles as follows: 45d37'12"

which makes Bucky Fuller a genius....roaming library stacks i couldn't believe 1/60 was rational but it goes back to the Sumarians, and if you are into Ancient Aliens, basically Aliens...why 1/60 and why does PI even exist....

pi is just math's way of saying round.
round and round and round and round and round.....
