ive been trying to do this problem but i dont know where to start....any help?(adsbygoogle = window.adsbygoogle || []).push({});

let v be a vector of length 9 in the direction 65degrees south of west.

if u has the same direction as v, and if 3|u| = 2|v|, then which of the following can be used to describe u?

u = 5.705i + 12.235j

u = -2.536i - 5.438j

u = 2.536i + 5.438j

u = -5.705i - 12.235j

none of these
