Ok this is a question about vectors that I've been trying to answer for hours so I'd love some help. The question is: What is the change in velocity of a boat if its original velocity is:
5m/s at 30 degrees E of N
and its final velocity is:
6m/s at 60 degrees E of N

I think it is answered using trigonometry but I cant work out how to draw the diagram. Vectors seem to be draw in a weird way compared to just straight lines.

So normally we measure our angles from the horizontal axis.
So let's label those angles,|dw:1398840080362:dw|
