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^^
How did you get a value for the opposite side without adding another variable to the mix though?
The furthest I can get without doing so is:
cos θ = 1 / x
tan θ = sin θ / cos θ = sin θ * x
edit:
The Law of Cosines!!
Lol figured it out, thanks for the little push in that direction
