See Figure 6.23. The four-sided, closed traverse has the following angles and distances: A = 51°23' AB = 713.93 ft N 67°11' E B = 105°39' ВС 3D 606.06 ft C = 78°11' CD = 391.27 ft D = 124°47' DA = 781.18 ft D The bearing of AB is N 67°17' E. (a) Perform a check for angular closure. (b) Compute both bearings and azimuths for all sides. (c) Compute the latitudes and departures. (d) Compute the linear error of closure and the precision ratio. FIGURE 6.23 Sketch for Problem 6.12.
