You are given three displacement vectors: with magnitude 5.0 m in the direction of 60o below the negative xaxis, vector, has an xcomponent of +2.5 m and a ycomponent of +6.0 m and vector has magnitude of 2.5 m in the negative yaxis.

A = 5m[240o]
B = 2.5+6i
C = 2.5i
X = 5*cos240 + 2.5 = 0
Y = 5*sin240 + 6  2.5 = 0.83
D = 00.83i = 0.83m[90o].
