Question
### Explorer Displacement Calculation

**Problem Statement:**
While exploring a cave, an explorer starts at the entrance and moves the following distances: She goes 250 m east, 102 m at an angle 30.0° south of east, and 185 m north. Note that the figure is not drawn to scale. Find the horizontal component \( D_x \) of the resultant displacement from the cave entrance measured in meters. **(Give the number only).**

**Figure Explanation:**
- The diagram shows an initial point labeled "Cave entrance."
- From this initial point, there is a horizontal line extending to the right (east) indicating the first movement of 250 m east.
- From the end of the 250 m east movement, there's another vector extending at a 30° angle south of east indicating the 102 m movement.
- Finally, there is a vertical line indicating the explorer's 185 m move towards the north.

**Instructions:**
Calculate the resultant horizontal displacement \( D_x \) by considering the components of each segment of the explorer's path.

**Answer Format:**
Provide the horizontal component of the resultant displacement in meters.

**Graph/Diagram Details:**
- A coordinate system with the origin at the "Cave entrance."
- Vectors representing movements: 
  - 250 m directly to the right (east).
  - 102 m at 30° south of the east.
  - 185 m vertically upwards (north).
- Angles and directions are correctly labeled.

---

When you have calculated the resultant horizontal displacement, ensure to only input the number value in meters.
