Please show me how to find the bearing of these angles:
1. 90....my answer is North
2. 315....ny answer is South East
Find the bearing of the following points:
1. (4,7)...my answer is N29 45'
I used tan....so tan^-1(7/4)=60.255
so 90-60.255 = N2945'E
is this right?
2. (-6,0)....I ondt know how to do this but I think it is 180
3. (0,-10).....I don't know how to do this but I think it is 270
*****if #2 and #3 are right....is it because at those points, it is just the degree of that quadrant?

You always take bearings by facing North. The angle is stated as a clockwise direction from the North.
So "90" is East, not North.
