List the steps involved in making elementary traverse computations.
1. Given the following tabulations are observed and calculated data for a traverse. Balance the latitudes and departures by the COMPASS RULE and compute for the area of the closed traverse by DOUBLE PARALLEL METHOD (DPD). Tip: Before you compute for the area of the closed traverse, you must first adjust the latitudes and departures.

When the measured angle in vertical plane using a total station (=zenith angle) is 16 24'45", what is the vertical angle for the trigonometric surveying? 3.
Given in the accompanying data are the adjusted latitudes for AB (305.70), BC (-101.44), CD (-97.65), DA (-106.61) and adjusted departures for AB (125.50), BC (189.39), CD (-43.08), DA (-271.81) of a closed traverse. If the X and Y coordinates of corner A are 250.50 and 725.35 meters, respectively, the X and Y coordinates of corner D are, respectively, • 357.11 m and 997.16 m • 831.96 m and 522.31 m • 522.31 m and 831.96 m • 464.76 m and 1040.24 m • 106.61 and 271.81 m
13. A surveyor needs to determine the coordinate of an inaccessible location, point C. Setting up on point A, they sight point B (due east of point A) and set 0 on their total station. The measured distance between A and B is 400 m. The surveyor points the total station at point C (north of point B and east of point A) and reads an angle to the right of 340°20'15". Given that the UTM coordinate of point A is 680100.455 mE, 4912081.750 mN (UTM 17T, NAD83) what are the coordinates of points B and C?
