### Coordinate Calculation for a Closed-Polygon Traverse

#### Problem Statement:

Given the data for a closed-polygon traverse, balance the traverses by coordinates using the compass rule. The data is provided in the table below:

| **Course** | **Bearing**       | **Length (ft)** |
|------------|-------------------|-----------------|
| AB         | N8°17'02"E        | 403.73          |
| BC         | N87°02'05"E       | 622.63          |
| CD         | S14°47'06"W       | 653.16          |
| DA         | N68°43'20"W       | 550.84          |

#### Task:

Compute the preliminary coordinates in feet if \( X_A = 9500 \) and \( Y_A = 11000 \).

**Express your answers in feet to two decimal places separated by commas**

#### Input Box:

\( X_B, Y_B, X_C, Y_C, X_D, Y_D = \) [Input Box]

---

#### Instructions:

1. Enter your computed coordinates in the input box provided, in feet, to two decimal places, and separated by commas.
2. Use the provided bearing and distance data to calculate the coordinates for each point (B, C, D) using the initial coordinates for point A and the compass rule.

---

#### Explanation of Diagram:

This section includes an interactive input box for entering the coordinates. The input box is shown as a text field with an accompanying instructional label indicating what values need to be input and in what format.

- \( \boxed{\text{X}_B, \text{Y}_B, \text{X}_C, \text{Y}_C, \text{X}_D, \text{Y}_D \text{ = }} \) [Input Area]
  
This text field is where students will input their answers based on the calculations.

---

**Note:** Ensure to use appropriate formulas and apply the compass rule to balance the given traverse correctly.
