my problem is this: √(4800)=√((80cos ̂)^2+(80sin ̂)^2)(adsbygoogle = window.adsbygoogle || []).push({});

pretty simple i no but i still keep making mistakes somewhere.

i can get it down to: 4800/6400=(cos ̂)^2 + (sin ̂)^2

but then i get a little stuck.

by the way ̂=thetre=unkown angle.

good luck

i need it.
