1) find values for 0-360 for which:
I though about using the RCosx, Rsinx but didnt get the right answer,
2) solve for 0-360
Im thinking i should use addition formulaes but then didnt know what to do.
3) solve for 0-pi
do i used sin2x=2sinAcosB here? then how do i get just sin?
4) sinx=cos^2x for 0-360
i just dont seem to be able to do trig anymore!

Rcos(x-a)=Rcosxcosa + Rsinxsina
R= square root of 50
Hopefully you can solve x from here
