Homework Statement
Three vectors a ,b c, and each have a magnitude of 42 m and lie in an xy plane. Their directions relative to the positive direction of the x-axis are 29°, 197°, 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?
