For the following traverse data, compute the estimated error in each angle if o, = ±3", o, = ±2", o, = o, = ±0.005 ft, and the angles were observed four times (twice direct and twice reverse) using the repetition method. Does the traverse meet acceptable angular closures at a 95% level of confidence?

fundamentals of surveying. ANGLE TO THE RIGHT TRAVERSE. A five-sided closed traverse proceeds in a clockwise direction and the angle to the right at each station were observed as follows: A = 270° 45’, B = 268° 43’, C = 203° 22’, D = 256° 20’, and E = 260° 25’. Determine the error in the sum of the angles. Adjust the angular values observed on the assumption that the error is the same for each angle. Tabulate all observed and adjusted values accordingly.

A line of three-wire differential levels goes from benchmark Gloria to benchmark Carey. The length of the line was determined to be 2199 m. The instrument had a stated compensator accuracy of ±0.3″. The instrument-rod combination had an estimated reading error of ±1 mm per km. The instrument is found have a inclined collimation error of 1.0 mm per km so the sight distances were kept to approximately 50 ± 5 m. If the observed difference in elevation is 15.601 m, what is the estimated error in the final elevation difference?
A line of three wire differential levels goes from benchmark Gloria to benchmark Carey. The length of the line was determined to be 1487 m. The instrument had a stated compensator accuracy of ± 1.5 mm/km. The instrument-rod combination had an estimated reading error of ±0.2 mm per 40 m. Sight distances were consistently kept to approximately 50 ± 5 m. If the observed difference in the elevation in 23.4516m, what is the estimated error in the final elevation difference?
A slope distance between two points P and Q is measure using a laser EDM, giving a corrected slope distance of 13,978.811m. The elevation of the lower point P is 470.381m. Reciprocal vertical angles are measured at P = +2°12’15”, and at Q = - 2°19’15”. Assume the instrument and target are at the same height above the ground at the two stations.What is the elevation of point Q? using the average values of the results obtained by both vertical angles.
