While surveying a cave, a spelunker follows a passage 190 m straight west, then 230 m in a direction 45.0° east of south, and then 270 m at 30.0° east of north. After a fourth unmeasured displacement, she finds herself back where she started. Part A Find the magnitude of the fourth displacement. Express your answer with the appropriate units. T4 = μÃ Value Units ?
