(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] 3 vectors using south, northeast, and west

1. The problem statement, all variables and given/known data

A particle undergoes the following consecutive displacements: 3.80 m south, 8.40 m northeast, and 14.0 m west. What is the resultant displacement?

2. Relevant equations

3. The attempt at a solution

This means that I have 3.80j, 8.4i, and 14.0k, right? I could then add up all of the x components and y components, right? or do I need to use the law of cos?

thank you very much
