The figure shows three displacement vectors A, B, and C. These vectors are arranged in tail-to-head fashion, and they add together to give a resultant displacement R, which lies along the x axis. Note that vector B is parallel to the x axis. What is (a) the magnitude of vector and (b) its directional angle ?
