WOO who i got it! thanks!

if i do that then i get 4.92 which apparently still aint right, unless I am doing something wrong mathwise, i took the inverse cosine of 0.278 which was 73.9then divided it by 15. and got 4.92.

then i got 0.289 when i tried again, but it still wasnt right

ugh it still didnt work out right, i got like 0.0289 >_<
