(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two forces applied to a bracket, Fu and Fv. The Resultant(R) of the two forces has a magnitude of 725 lb and a direction shown in my pic. Determine the magnitude of the two forces(Fu and Fv).

2. Relevant equations

So far, I've just used law of Sines, but I'm sure law of Cosines.....pythagorean theorm....etc.

3. The attempt at a solution

Ok basically, I've got the answers in the back of the book...but I'd like to know how to get the answers. To tell ya the truth, a picture(or a good word explaination) would be very helpful...when applying the degrees used(so I know what "corner" they are coming from.

I drew my picture(see the attachment)....and I've found many of the angles, using the law of sines/pythagorean.

Then, for Fv I did this(and it seems to be the right answer too.....I think I understand what I did, kinda....but I guess not good enough to do Fu).

Here's what I did:

Fv = (sin(75.9638) * 725lb) / sin(132.274) = 950.559lb

Thanks in advance for the help!

I've done a few more on my own, thanks to the last help on here I had....but, I still need more instruction I guess. This one confuses me, because you are given the resultant instead of the forces, and one of the forces points in a different direction.
