Best ResponseYou've already chosen the best response.1memory tricks may be: theres a SIGN, OVER there COSy up NEXT.TO someone you like

Best ResponseYou've already chosen the best response.1hyp is the side that is neither over or next.to :) its the slanted part of the rt tri

Best ResponseYou've already chosen the best response.0oh so then to 5\[5 \over 119?\]

Best ResponseYou've already chosen the best response.1if we observe the X angle: over = sqrt(119) next.to = 5 that leaves hyp=12 sin X = over/hyp cos X = next.to/hyp its just a matter of filling in the proper parts

Best ResponseYou've already chosen the best response.0ok so then it would be 119/12 for sin and 5/12 for cos?

Best ResponseYou've already chosen the best response.1yes, but dont forget to notate that 119 properly: \(\sqrt{119}\)

Best ResponseYou've already chosen the best response.0ok so if i did it write then the sin would be 130.904?

Best ResponseYou've already chosen the best response.0and cos would be 0.416?

Best ResponseYou've already chosen the best response.1your cosine is fine you hit some wrong buttons on your calculator for the sin tho

Best ResponseYou've already chosen the best response.0oh really?oh yeah I did that wrong. Thank you!!

Best ResponseYou've already chosen the best response.1a good dbl chk is that sin^2 + cos^2 = 1 sin^2 + (5/12)^2 = 1 sin^2 + 25/144 = 1 sin^2 = 1  25/144 sin^2 = 119/144 sin = sqrt(119)/12 but then youd still ahv eto hit the right buttons :)
