Best ResponseYou've already chosen the best response.0So I leave it as sq root 34. Then cos x is 5/sq root 34 and sin x is 3/sq root 34. Is that correct?

Best ResponseYou've already chosen the best response.0Sorry, why are you multiplying by sq rt 34, then dividing by 34 ?

Best ResponseYou've already chosen the best response.1It is not considered simple form to have a radical in the denominator.

Best ResponseYou've already chosen the best response.1\[\frac{5}{\sqrt{34}}\times \frac{\sqrt{34}}{\sqrt{34}}=\frac{5\sqrt{34}}{34}\]
