### Closed-Polygon Traverse Data The table below presents the data for a closed-polygon traverse, commonly used in surveying to determine the perimeter and angles of areas. | Course | Azimuth | Length (m) | Interior Angles | |--------|----------------|------------|---------------------| | AB | 75°14'47'' | 521.674 | A = 12°25'31'' | | BC | - | 454.765 | B = 48°19'25'' | | CD | - | 435.926 | C' = 126°37'24'' | | DE | - | 426.558 | D = 46°03'36'' | | EA | - | 109.434 | E = 306°34'19'' | #### Explanation of the Table Columns: 1. **Course:** This column indicates the segments of the traverse, labeled as AB, BC, CD, DE, and EA. 2. **Azimuth:** The azimuth is the compass direction from one point to another and is provided in degrees (°), minutes ('), and seconds (''). Only the azimuth for segment AB is given as 75°14'47''. 3. **Length (m):** The length of each course or segment is given in meters (m). 4. **Interior Angles:** The interior angles at each vertex of the polygon are specified in degrees (°), minutes ('), and seconds (''). This data aids in the precise mapping and calculation of areas within the polygon, essential for multiple applications in civil engineering, geography, and urban planning.
