In this problem, you will need to use trigonometric functions to break down the distance traveled by the ship into its westward and southward components. Specifically, you use the bearing to create a right triangle and then apply sine and cosine functions to find these components.
Given:
- Distance traveled: \( 95.5 \) miles
- Bearing: \( S 55.3° W \)
To calculate the westward (X) and southward (Y) components:
1. \( X = 95.5 \cos(55.3°) \)
2. \( Y = 95.5 \sin(55.3°) \)
Ensure that your calculator is in degree mode when performing these calculations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F29eaf221-c72e-4b9c-a681-25e14c4a1cc7%2Fcfa42258-27e1-46b8-b26b-b60143a14a04%2Fw5p3on_processed.jpeg&w=3840&q=75)
