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 appropriate scale drawing to determine the magnitude and direction of the fourth displacement. What is the spelunker’s displacement?
