Problem 3-9 - Vector sum - Part 2

Find the magnitude and direction of the sum of the vectors \(A + B + C\) using the component technique. Assume two significant digits.
\(A = 20\; km\) north, \(B = 30\; km\) east, \(C = 50\; km\; 55 ^\circ\) west of north.

The three vectors \(\text{A, B, C}\) must now be placed in the chosen coordinate system. Which drawing is correct?

(A)

(B)

(C)
