I know that for the magnitude, since both vectors have different directions I cannot just add them together. I am not sure where to go from here.

**Damon**, Sunday, May 27, 2012 at 4:05pmDivide both vectors into East (x) and North (y) components

First vector:

east1 = 254 cos 30 = 220

north1 =254 sin 30 = 127

Second vector

east 2 = - 178

north2 = 0

now add east components

220 - 178 = 42 east

now the north components

127 + 0 = 127

so

magnitude = sqrt (42^2+127^2) = 134

tan e = 127/42 = 3.02

so e = 71.7 degrees north of east
