2. Displacement 170 mi north length = _____ in.
3. Displacement 210 at 45° south of west length = _____ in.
4. Displacement 145 mi at 60° north of east length = _____ in.
5. Displacement 75 mi at 25° west of north length = _____ in.
6. Displacement 160 at 72° west of south length = _____ in.
7–12 Draw the vectors in Problems 1 through 6 using the scale indicated.
