Three vectors a, b, and c each have a magnitude of 54 m and lie in an xy plane. Their directions relative to the positive direction of the x axis are 27°, 193°, and 314°, respectively. What are (a) the magnitude and (b) the angle of the vector a + b + c, and (c) the magnitude and (d) the angle of a -b +c ? What are (e) the magnitude and (f) the angle of a fourth vector d such that ( a+b ) - ( c+d ) = 0?
