Hello! I have this question. I think I have the answer but am unsure if I am correct. Could someone check it for me? I got: the vector has a magnitude of 143.54m west 49.09 degrees from south. A spelunker is surveying a cave. She follows a passage
180 m straight west, then 210 m in a direction 45° east of south,
and then 280 m at 30° east of north. After a fourth displacement, she finds herself back where she started. Use a scale drawing to determine the magnitude and direction of the fourth displacement.
