?? Usually a resultant is just the sum of the two forces.
Just add F1 and F2. You just have to break them down into i and j components first, which you have shown you can do.
Or, use the law of cosines. The angle between F1 and F2 is 105°, so the length of F1+F2 is just the diagonal of the parallelogram formed by them. That is,
d^2 = 850^2 + 425^2 - 2*850*425 cos75°
Suppose that F1 = 850 N and F2 = 425 N . Determine the magnitude of the resultant force.

I think i need to draw a line from F1 to F2 on the figure and work out the problem. Not sure whaat to do . I forgot what the resutant force is.
