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
