Three vectors , , and , each have a magnitude of 44.0 m and lie in an xy plane. Their directions relative to the positive direction of the x axis are 30.0 ˚, 191 ˚, and 315 ˚, respectively. What are (a) the magnitude and (b) the angle of the vector (relative to the +x direction in the range of (-180°, 180°)), and (c) the magnitude and (d) the angle of in the range of (-180°, 180°)? What are (e) the magnitude and (f) the angle (in the range of (-180°, 180°)) of a fourth vector such that(a+b) ?
