You have the adjacent (6mm) and want to work out the opposite so you have to use tan.

Tan23 = x/6 where x is ??mm

[Bibio]

English for the dumb people please. lol

Think its 2.5468.

[SvNewbie]

God, it's been a while since I've done these!

tan 23 = o / 6mm.
0.424474816 = o / 6mm
o = 0.424474816 * 6
o = 2.546848897

So 2.5mm, which looks about right against the diagram.

[Bibio]

aha. so using a calculator we go:

23, tan, x, 6, = ??

i knew you lot would know... :-)

Very useful and straightforward formula, and if you remember SOH-CAH-TOA sound like 'soccer tower' you won't forget it.

[ClunkintheUK]

an inch?

Slightly more than a 1/10th of an inch. In fact 0.0068 mm more that a tenth inch.

[The Guru]
