Well till I went back and reread. I was lost. Years ago I cound really shine as a pipefitter because of this. Think in early 80s I paid around 10 bucks for a calculator which would do this. Forgot the name, think it was a model 509 or 510. I never learned to do this on paper or by the trig tables in back of pipefitters books. Anyway you know the drill. Plus I can't spell this shit. *cough-pythagoreantheorem-cough*
