PROBLEM 02 Find the angle between two vector forces whose maanitudes are F and 3F and the magnitude of whose resultant 19 3F.

At what angle Θ must the 800-lb force be applied in order that the resultant R of the two forces have a magnitude of 860 lb?

A 150 Newton force is pulling 70 degrees above the horizontal and somewhat to the right. Tell me first the vertical and second the horizontal magnitudes in Newtons of the two smaller vectors that could be added to get this larger vector.
