1. The interior angle of a six-sided closed traverse were measured as follows: A 36 54' 23" B = 145 34' 12" C = 182 45' 23" D = Not measured E= 87 24' 09" F = 134 16 02" If all observed angles are assumed to be correct, determine the interior angle at D. Also, determine the bearing of each line if the bearing of line of line EF is S 42' 23'W.

Bearing for line EA and internal angles for the corners of the following traverse are given. Begin from point E and moving clockwise 1. Determine the azimuths of lines ED, DC, CB, BA, AE and EA (do not forget, first you have to convert the given bearing to azimuth). 2. Is the azimuth for EA the same as given? If not, calculate the error that occurs at EA. 3. For each side (ED, DC, CB, BA and AE) calculate the bearing. A N 68°39'39" E 129°36'45" E 87°35'45" 114°29'00" B 115°05'08" 93°13'22"

7. A = 51°23' B = 105°39' C=78°11' D=124°47' The four-sided, closed traverse has the following angles and distances: AB= 713.93 ft BC=606.06 ft CD=391.27 ft DA=781.18 ft The bearing of AB is N 64°40'E A N 64°40' E D B C 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.

Horizontal line will have a vertical angle of 90°, this angle is called ..... Select one: a. Bearing b. Just an angle of line c. Azimuth O d. Zenith

Balance the interior angles of the closed polygon shown below and determine the bearings AND azimuths for each side using the adjusted angles.

Find the bearing and azimuth for the traverse. Angle A bearing is going NW. Angle D and I bearing are going East. Number of side are 10. (n-10)180=1440 degrees.

The bearing of a line AB in a closed traverse ABCA is 137°30' and its length is 125.8 m. The coordinates of A in x-y plane is (-5 m, 123.45 m). If the line BC passes through the origin and the x-coordinate of point C is same as that of A, then the length BC is equal to m (round off to two decimal places).
