hyp is the side that is neither over or next.to :) its the slanted part of the rt tri

sorry math isnt the best for me lol

if 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

ok so then it would be 119/12 for sin and 5/12 for cos?

yes, but dont forget to notate that 119 properly: \(\sqrt{119}\)

ok so if i did it write then the sin would be 130.904?

and cos would be 0.416?

your cosine is fine you hit some wrong buttons on your calculator for the sin tho

a 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 :)
