Can someone tell me how to add these 3 vectors to show that they all add up to zero. Even though there is 3 vectors somehow there is 5, don't really understand. The diagram is drawn below.If unclear, the two angles are 30 degrees and each length is 1. Thanks in advance.(adsbygoogle = window.adsbygoogle || []).push({});
