Best ResponseYou've already chosen the best response.1Ok How about this? Look at arccos(radical 3/k) Label this part y or whatever. So we have \[y=\arccos(\frac{\sqrt{3}}{k})\] which means \[\cos(y)=\frac{\sqrt{3}}{k} \] Label a right triangle with the adjacent side of y being length sqrt(3) and label the hyp with the length k. Then find the opposite side of the angle y using the Pythagorean Theorem.

Best ResponseYou've already chosen the best response.1Then find tan(y) (which we also know as \[\tan(\arccos(\frac{\sqrt{3}}{k}))\])
