Repeat the problem two problems prior, but for the second leg you walk 20.0 m in a direction 40.0o north of east (which is equivalent to subtracting B from A - that is, to finding R' = A - B).
(b) Repeat the problem two problems prior, but now you first walk 20.0 m in a direction south of west and then 12.0 m in a direction 20.0 0 east of south (which is equivalent to subtracting A from B- that is, to finding R" = B - A = -R'. Show that this is the case.
