Find Combined Vector Given Angles: Is It Possible?

[Femme_physics]

If you're only given the combined vector and you're asked to find the two vectors that made up this combined vectors, and you got all the angles you need that relate the combined vector to the vectors you've combined. Is it possible to get the answer from that info alone? If so, how?

Hi Femme_physics!

Yes, either draw a vector triangle and use the sine rule, or use components parallel and perpendicular to the combined vector.

Would you like to try one, so that we can see if you're getting it right? ​

Ah tiny-tim...you're recognized me in my disguise have you? ;)

Yes, I would! I tried that now..no triangles I draw seem to work!

So I won't get a warning for askig a HW question, try this link:
