    Answer:

    156.28m

    Explanation:

    Given;

    His displacement is 900 m 80° North of west

    Let North and South represent y axis and west east represent axis.

    the x component of his displacement vector can be written as;

    dx = dcosθ

    Where d is the resultant displacement = 900m

    θ is the angle with the x axis = 80°

    Substituting the values;

    dx = 900cos80°

    dx = 156.2833599002 m

    dx = 156.28 m

    the x component of his displacement vector is 156.28m
