hi! can't understand what does "bearing of 325 degrees" in trigo means.

For example take this problem of 10th standard of IGCSE board-

Two boats set off from X at the same time.Boat A sets off on a bearing of 325 degrees and with a velocity of 14kmperhour.Boat B sets off on a bearing of 235 degrees with a velocity of 18kmper hour.Calculate the distance between the boats after 2.5 hours

kindly explain how to get the triangle when bearing in degrees is given.
