Since it is given the angle with respect to the Y axis the x component is given by the sine of the angle. Since we don't know which quadrant the velocity vector is

in, only that it is in the lower half of the plane where y is negative, the two possible x velocities are

5sin (60) = 4.33

-5sin (60) = - 4.33
