    The magnitude of a vector is defined as the square root of its components squared.

    We have then that the magnitude is:

    v = root ((7.50) ^ 2 + ( - 6.10) ^ 2)

    v = 9.67 units

    The direction of the vector is:

    x = Atan (vy / vx)

    x = Atan (( - 6.10) / (7.50))

    x = - 39.12 degrees (measured from the x axis)

    answer:

    v = 9.67 units

    x = - 39.12 degrees (measured from the x axis)
