Answer:

To compute the departures and latitudes, you need to use the following formulas:

- Departure = Length * sin(Azimuth)

- Latitude = Length * cos(Azimuth)

To compute the coordinates, you need to use the following formulas:

- Easting = Departure + Previous Easting

- Northing = Latitude + Previous Northing

To compute the linear closure and the relative precision, you need to use the following formulas:

- Linear closure = sqrt((Sum of Departures)^2 + (Sum of Latitudes)^2)

- Relative precision = Linear closure / Perimeter

I have created a table with the answers for you. You can copy and paste it into your worksheet.

| Course | Length (m) | Azimuth | Unbalanced | Departure | Latitude | Easting | Northing |

|--------|------------|---------|------------|-----------|----------|---------|----------|

| 1-2 | 100 | 0 | 0 | 0 | 100 | 100 | 100 |

| 2-3 | 100 | 90 | 0 | 100 | 0 | 200 | 100 |

| 3-4 | 141.42 | 135 | -0.01 | 100 | -100 | 300 | 0 |

| 4-1 | 141.42 | -135 | -0.01 | -100 | -100 | 200 | -100 |

| Linear closure | Relative precision |

|------------------|--------------------|

| 200 | 0.707 |
