Draw the vectors involved.
resolve each vector into its x- and y-components
(a) add them up and use the distance formula for the resultant.
(b) If the ship started at (0,0) and ended at (x,y), then the bearing of the port is θ (measured counterclockwise from the positive x-axis), such that
tanθ = y/x
Then convert that to a 0-360 bearing.
A ship leaves port 21km on a bearing of 032 degree & 45km on a bearing of 287degrees
a, calculate it's distance from the port
b, calculate the bearing of the port from the ship
