3.04-(0.3/2tanB) where B=30%
It is a formula on an engineering drawing we have been sent. (for information)
+130071 I believe you must mean "30° " rather than "30%"
So we have
3.04 - [ (.3/2) * tan (30°) ] =
3,04 - [ .15 * (1 / √3 ) ] =
3.04 - [ .15 √3 / 3 ] =
3.04 - .05 √3 ≈ 2.9534
Thank you.
Yes it is degree, not percent 
We get an answer sililar to that, but it makes no sense on the drawing we have been sent.
We just needed to make sure we weren't missing something.
Thank you very much. (I think this site might be a good find.....i'll bookmark it straight away )
