    Answer:

    Explanation:

    If a force of 20N is situated at 30° south west, the x and y component of the vector will be expressed as:

    Fx = -Fcos 30° and Fy = -Fsin30°

    They are but negative because the force acts in the third quadrant of a four cardinal point

    Fx = -20cos30°

    Fx = -20(√3/2)

    Fx = -10√3N

    Hence the -x component if the force is -10√3N

    Fy = -20sin30°

    Fy = -20(1/2)

    Fy = -10N

    Hence the y-component is the vector is -10N
