You are given a vector in the xy plane that has a magnitude of 89.0 units and a y component of -57.0 units.
a) What are the two possibilities for its x component
b) Assuming the x component is known to be positive, specify the magnitude of the vector which, if you add it to the original one, would give a resultant vector that is 80.0 units long and points entirely in the −x direction.
c) Specify the direction of the vector.
