Find y if the point (15, y) is on the terminal side of θ and\[\cos\theta=\frac{15}{17}\](Enter your answers as a commaseparated list.)
My result was \[\pm8\]but I'm told that it's the wrong answer. ッ

Best ResponseYou've already chosen the best response.1\[x=15,y=8,r=17\]\[\sin\theta=\frac{8}{17},\cos\theta=\frac{15}{17},\csc\theta=\frac{17}{8},\sec\theta=\frac{17}{15}\]I would have kept going but I'm not sure if I'm going in the right direction.
