A cave explorer is surveying a cave. He follows a passage 100m straight east, then 50m in a direction 30 degree west of north, then 150m at 45 degree west of south. After a fourth unmeasured displacement, he finds himself back where he started.Using a scale drawing, determine the fourth displacement(in magnitude and direction).

Add the vectors component by component and see where the resultant components are with respect to the starting point.
