A spelunker is surveying a cave. She follows a passage that takes her a distance 175 m straight west, then a distance 202 m in a direction 45.0 degrees east of south, then a distance 279 m at 30.0 degrees east of north. After a fourth unmeasured displacement she finds herself back where she started.

A) Use the method of components to determine the magnitude of the fourth displacement.

B) Use the method of components to determine the direction of the fourth displacement.
