Ship Distance Dfbbf0
1. **Problem statement:** A ship sails 200 km on a bearing of 243.7 degrees. We need to find how far south and how far west the ship has traveled.
2. **Understanding bearings:** A bearing is measured clockwise from the north direction. A bearing of 243.7 degrees means the ship is sailing in a direction 243.7 degrees clockwise from north.
3. **Breaking down the bearing:** Since 243.7 degrees is between 180 and 270 degrees, the ship is moving in the southwest quadrant.
4. **Using trigonometry:** To find the south and west components, we use sine and cosine functions relative to the angle from the south or west axis.
5. **Calculate the angle from the south direction:** The south direction is at 180 degrees, so the angle from south is $$243.7^\circ - 180^\circ = 63.7^\circ$$.
6. **Southward distance:** The southward component is the adjacent side to this angle, so
$$\text{South} = 200 \times \cos(63.7^\circ)$$
7. **Westward distance:** The westward component is the opposite side to this angle, so
$$\text{West} = 200 \times \sin(63.7^\circ)$$
8. **Calculate values:**
$$\cos(63.7^\circ) \approx 0.445$$
$$\sin(63.7^\circ) \approx 0.896$$
9. **Final distances:**
$$\text{South} = 200 \times 0.445 = 89 \text{ km}$$
$$\text{West} = 200 \times 0.896 = 179.2 \text{ km}$$
**Answer:**
(a) The ship has traveled approximately 89 km south.
(b) The ship has traveled approximately 179.2 km west.
