    Answer:

    50 degree.

    Explanation:

    Given that the components of vector A are given as follows: Ax = 5.6 Ay = -4.7

    The angle between vector A and B in the positive direction of x-axis will be achieved by using the formula:

    Tan Ø = Ay/Ax

    Substitute Ay and Ax into the formula above.

    Tan Ø = -4.7 / 5.6

    Tan Ø = -0.839

    Ø = tan^-1(-0. 839)

    Ø = – 40 degree

    Therefore, the angle between vector A and B positive direction of x-axis will be

    90 – 40 = 50 degree.
