√33/ 4
7•√33/ 33
√33 /7
4•√33/33

I think that is a) \(\sqrt{33}/4\)

urg I couldn't figure out if it was a or c because I wasn't sure if 4 or 7 should be the denominator

cot B = \(\frac{1}{tanB}\) right ?

@rebeccaskell94 First step is to find AB we know that using Pythagoras \[BC^2=AB^2+AC^2\] Find AB from here \[\cot =\frac{adjacent}{perpendicular}=\frac1 {\tan}\]

tan B = opposite/adjacent opposite = 4 adjacent = ??? We will find adj. by pythagoras theorem

\[base^2+perpendicular^2=hypotenuse^2\] Adjacent = \(\sqrt{33}\) hence we have tan B = \(\frac{\sqrt{33}}{4}\)

Yes! Very much so. I'm writing it down now so I remember the basic idea :) Thank you so much!

See http://www.khanacademy.org/math/trigonometry/v/basictrigonometry for a video on sin,cos, tan defs using SOHCAHTOA a the co functions are harder to remember!

SOH CAH TOA much better sine = opposite / hypotenuse cosine = adj. / hypotenuse tan = opposite / adj. right ?
