**Keith**, Monday, June 18, 2012 at 9:49pmYou have four vectors.

For each one resolve them into North and east components.

Adding the North components.

N= 75 + 0 + 125 sin(30) - 150 = - 12.5 m

And adding the east components we get

E = 0 + 250 + 125 cos(30) + 0 = 358.25

The magnitude of the result is found by Pythagoras' theory

C = sqrt (a^2 + b^2)

= 358 m to three significant figures.

And the angle is south of east.

found by arctan (12.5/358.25)

= 2 degrees south of East.
