If the magnitude of the resultant force is to be 500 N, directed along the positive y axis, determine the magnitude of force F and its direction theta.

If theta = 60° and F = 450 N , determine the magnitude of the resultant force and its direction, measured counterclockwise from the positive x axis.

Determine the magnitude of the resultant force F_R = F₁ + F₂ and its direction, measured counterclockwise from the positive x axis.
