**Steve**, Wednesday, January 9, 2013 at 10:36amI assume you want the resultant force? Just convert the polar coordinates to rectangular, add them, and convert back to polar:

(100,50°) = (64.28,76.60)

(50,160°) = (-46.98,17.10)

(80,-20°) = (75.18,-27.36)

add them to get

(92.48,66.34) = (113.81,35.65°)
