## Homework Statement

Two forces P and Q are applied as shown to the corners A and B of a square plate. Determine their magnitudes P and Q and the angle (weird B) knowing that their resultant R has a magnitude R = 120 N and a line of action passing through O and forming an angle of 30 degeres with the x axis.

## Homework Equations

## The Attempt at a Solution

(R = 120 N @ 30 degrees) = sqrt ( (Px+Qx)^2 + (Py+Qy)^2) )

I could go further on that but know that somehow a moment is involved here and don't know how to place it. Thanks.
