A has the magnitude 10.9 m and is angled 56.3° counterclockwise from the positive direction of the x axis of an xy coordinate system. Also,   B→=(10.6 m)î+(7.05 m)ĵ on that same coordinate system. We now rotate the system counterclockwise about the origin by 21.8° to form an x'y' system. On this new system, what are (a)A→ and (b)B→, both in unit-vector notation?
