**Henry**, Saturday, November 16, 2013 at 6:16pmV1 + V2 = 1200[70o] + 900[205o]

X = 1200*cos70 + 900*cos205 = -405.3

Y = 1200*sin70 + 900*sin205 = 747.3

tanAr = Y/X = 747,3/-405.3 = -1.84376

Ar = -61.53o = Reference angle.

A = -61.53 + 180 = 118.5o

Vr = Y/sinA = 747.3/sin118.5 = 850.3[118.5o] = Resultant vector.
