How do I calculate Draft angle?

I am attempting to build a 12 sided monopole section.

The dimensions are as follows

40" diameter at the bottom

31.73" diameter at top

45'-4 1/2" tall

.375" thick


I've drawn the bottom sketch, extruded it to length and applied the Thin Feature.


But I can't for the life of me figure out how to calculate the draft angle to give me the 31.73" diameter at the top.


How do I calculate this angle, or am I using the wrong feature to create this?


Thanks in advance!
