1. What is the angular closure for the following interior field angles of traverse ABCDEF, measured with equal precision? A. 87° 54' 14" B. 90° 32' 45" C. 102° 43' 31" D. 99° 24' 34" E. 156° 01' 55" F. 183° 23' 01" 2. Using the angles in the previous problem, how much adjustment is needed for each angle? 3. Using adjusted angles from above, and a direction for line AB of 274°, what is the direction for each line? Work clockwise about the traverse. 4. Provide the back azimuth for the following azimuths: 232° 12' 07" 156° 52' 17" 31° 32' 42" 5. Convert the following azimuths into bearings: a) 251° 43' 52" b) 111° 32' 59" c) 336° 32' 52" 6. Given two successive azimuths of a traverse 69° 21' followed by 220° 11', what is the counterclockwise interior angle between them? 7. a) b) c) 8. 9. Given two successive bearings of a traverse N 41° 35' E followed by N 87° 36' E, what is the interior angle between them? A 4410' line bears N 68° 11' 07" E. What is the latitude and departure of the line? A 956' line bears S 32° 53' 42" W. What is the latitude and departure of the line? 10. A 1436.32' line has an azimuth of 178° 52' 13". What is the latitude and departure of the line? 11. A 1233.45' line has an azimuth of 123° 24'. What is the latitude and departure of the line? 12. The closure in latitudes of a loop traverse is N 0.0635 feet; the closure in departures is W 0.0512 feet. What is the linear error of closure?
