1. I really don't understand bearings in triangles. I am doing M1 and although I can work out all the angles, sides etc., when it comes to the bearing I am just so confused.

For example: a body moves with velocity (-3i+5j)m/s. Taking the horizontal axis to be due east and the vertical axis to be due north, find the speed of the body and the direction it acts in.

Could someone please help me understand how to work out the bearing? I know that it is taken from clockwise from North. Maybe with a diagram?
2. haven't done m1 for a while so just a guess from what I vaguely remember?

Thank you so much for taking the time to do that! I think I had the diagram the wrong way round which was making it a bit difficult!
