The following table gives data of consecutive co-ordinates in respect of a closed theodolite traverse PQRSP.
The magnitude and direction of error of closure in whole circle bearing are
-
- 2.0 m and 45°
- 2.0 m and 315°
- 2.82 m and 315°
- 3.42 m and 45°
- 2.0 m and 45°
Correct Option: C
∑L = 400.75 + 100.25 – 199 – 300 = 2
∑D = – 300.5 + 199.25 + 399.75 – 200.5 = – 2
Error of closure = √(∑C)² + (∑D)² = √4 + 4 = 2√2
| tan θ = | = - 1 | |
| ∑L |
∴ θ = 315°
