Problem 3-9 - Vector sum - Part 4 (a)

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.

Sum    

Correct!

The \(x\) and \(y\) components of \(\text{B}\) are (in \(km\)):

Variable \(x\) \(y\)
(A) \(30\) \(0\)
(B) \(0\) \(30\)
(C) \(30\) \(30\)
