Please asap

He heads east 3 miles, turns and walks 1.5 miles north, and finally turns and walks 1.5 miles weat. What is his displacement?

Please answer part A and B with explanation

Vector A has a magnitude of 25 units and points in the positive y-direction. When vector B is added to A, the resultant vector A + B points in the negative y-direction with a magnitude of 17 units. Find the magnitude and direction of B? magnitude unit(s) direction ---Select--- +x +y

Vector A, which is directed along an x axis, is to be added to vector B, which has a magnitude of 2.30 m. The sum is a is directed along the y axis, with a magnitude that is 4.90 times that of A. What is the magnitude of A? Number i Units
