Problem:     Three forces are acting on a body. Determine the resultant vector that is acting on the body. Write the solution in component form, linear combinbation form, and as a magnitude and direction. Round your responses to the nearest tenth of a unit.

F1 = 22 Newtons at 78°
F2 = 66 Newtons at 92°
F3 = 59 Newtons at 21°
