Repeat the problem two problems prior, but for the second leg you walk 20.0 m in a direction 40.0º north of east Repeat the problem two problems prior, but now you first walk 20.0 m in a direction 40.0º south of west and then 12.0 m in a direction 20.0º 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.
