**1. Homework Statement**

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. Homework 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.
