### 1. Find the Distance of Line 3-4

From the table, the bearings and distances of lines 1-2, 2-3, and 4-1 are given. To calculate the distance of 3-4, we'll use the **Pythagorean theorem**, **sine law**, or **cosine law** as needed. 

However, without coordinates, solving it directly may need assuming coordinate values or using a trigonometric layout based on bearings and distances.
