To solve this problem, let’s break down the steps required based on the image you provided. We have a closed traverse with bearings and distances between stations, and we need to:

1. Complete the Table: Determine the coordinates for stations $B$, $C$, and $D$ by applying the bearings and distances, using the provided coordinates of station $A$ as a reference point.
2. Calculate Linear Misclosure: Determine how far off the computed ending point is from the starting point after completing the traverse.
3. Calculate Traverse Accuracy: This involves determining the ratio of the linear misclosure to the total traverse length.

Step-by-Step Solution Outline

1. Convert Bearings to Cartesian Changes: For each leg (e.g., $A \to B$), use the bearing and distance to calculate the changes in $x$ (East) and $y$ (North) coordinates. We can use: $\Delta x = d \cdot \cos(\theta)$ $\Delta y = d \cdot \sin(\theta)$ where $d$ is the distance and $\theta$ is the bearing.

2. Compute Coordinates: Using the coordinates of point $A$ (18.149 mN and 178.426 mE), apply the calculated $\Delta x$ and $\Delta y$ from the first step to find the coordinates for points $B$, $C$, and $D$ sequentially.

3. Calculate Linear Misclosure: After finding the coordinates of $D$, calculate the difference between $D$ and $A$ to check if they match. The discrepancy between the starting and calculated end point is the linear misclosure.

4. Calculate Traverse Accuracy: The traverse accuracy is given by: $\text{Traverse Accuracy} = \frac{\text{Linear Misclosure}}{\text{Total Distance}}$

5. Adjust Traverse Coordinates: Once we have the misclosure, we can distribute it across the traverse to correct each station’s coordinates and achieve a closed traverse.
