Question

What is the angular misclosure at a 95% confidence level?

BSGE students of Caraga State University conducted a rectangular traverse. The angles were observed using a Transit with 4 repetitions each. The distances were observed using a steel tape. The observed values of distances and their standard deviations are as follows: Standard Occupied Sighted Distance Station (m.) Deviation Station (m.) A В 123.28 + 0.03 В 207.17 ± 0.02 C D 121.22 + 0.02 D A 207.24 ± 0.04 The observed values of interior angles and their standard deviations are as follows: Standard Deviation (in seconds ) Backsight Occuppied Foresight Angle D A В 89.20687 ±41 A В C 90.239 +7 B 90.36119 +1 D A 90.20046 +26 What is the angular misclosure at a 95%, confidence level?
