How accurately should each 30.000 m distance have be measured so that the estimated total error would not exceed 0.050 m in a total distance of 600 m2 (surveying probable error with a theodolite 5. The interior angles of a nine-sided polygon are being measured instrument for measuring angles). Specifications require that the total estimated may not exceed ± 60 seconds. How accurately must each angle be measured?
