Answer: The west components of the walk = 4.7 miles
The south components of the walk = 8.1 miles (Approx)
Step-by-step explanation:
Since, the A hiker walks 9.4 miles at an angle of 60° south of west.
Thus,by the below diagram,
The west components of the walk = 9.4 × cos 60° = 9.4 × 0.5 = 4.7 miles
And, the south components of the walk = 9.4 × sin 60° = 9.4 × √3/2 = 9.4 × 0.866025404 = 8.1406388 ≈ 8.1 miles
