Hey,

This question is from a college math placement practice test that I took yesterday and I couldnt for the life of me remember how to evaluate this angle.

"In the right angle shown in the figure below, tan ( θ ) = _____ ?"

it was multiple choice but I only have access to the question itself and the answer which i selected (randomly, may I add =p).

Any help would be much appreciated, answer or otherwise, but i am most interested in the laws/formulas/ideas which allow you to evaluate this.

Thanks a million for any help

EDIT: the placement test is no calculator no notes, btw^^
