Best ResponseYou've already chosen the best response.1@rebeccaskell94 First step is to find AB we know that using Pythagoras \[BC^2=AB^2+AC^2\] Find AB from here \[\cot =\frac{adjacent}{perpendicular}=\frac1 {\tan}\]

Best ResponseYou've already chosen the best response.2tan B = opposite/adjacent opposite = 4 adjacent = ??? We will find adj. by pythagoras theorem

Best ResponseYou've already chosen the best response.2\[base^2+perpendicular^2=hypotenuse^2\] Adjacent = \(\sqrt{33}\) hence we have tan B = \(\frac{\sqrt{33}}{4}\)

Best ResponseYou've already chosen the best response.2SOH CAH TOA much better sine = opposite / hypotenuse cosine = adj. / hypotenuse tan = opposite / adj. right ?
