How about:
o = (COS(ASIN((170*SIN(A)))/180))*180) (COS(A)*180)

Thanks all, I guess I really deserved this.
As mentioned before, we were picking on each other in good fun or at the very least I was.  None of this was directed at you, we just use your O.P. to get us going which as you can see does not take much.  And yes we get distracted with Squirrels and other things with bushy tails also.   So do not take it heart. 

From your problem I can see it is above my pay grade so I will leave it to the more knowledgeable ones.
Cheers.

Whoops forgot to read page three of this thread.  Ahh excel to rescue.

The above post proves my point; that a well formed question will yield a well formulated answer.

Although, I wonder why any use of 'trig' would be needed to 'solve' the unknown angles; given that it was drawn correctly in cad to start with?

Writting a routine that draws all Steal Beams as structural members.  Can put into any configuration and in one configuration  need to know the plum cut programaticaly for ofset bearing points.  Yes I knew that it can be solved using lisp or a calculator but I had to prove it to understand it.
