A spelunker is surveying
a cave. She follows a passage 180
m straight west, then 210 m in a di-
rection 45° east of south, and then
280 m at 30° east of north. After a
fourth displacement, she finds her-
self back where she started. Use a scale drawing to determine the mag-
nitude and direction of the fourth displacement. (See also Problem 1.57
