    We calculate first for the normal force, Fn, which is equal to the product of the force and the cosine of the given angle,

    Fn = (15 kg) (9.8 m/s²) (cos 30°)

    Fn = 127.30 N

    Then, to calculate for the Fg, we multiply the normal force by the given coefficient.

    Fg = (127.30 N) (0.15) = 19 N

    The nearest value is letter A.
