Chapter 14 Homework
1. What is the angular closure for the following interior field angles of
traverse ABCDEF, measured with equal precision
720
2. Using the angles in the previous problem, how much adjustment is needed
for each angle?
None
3. Using adjusted angles from above, and a direction for line AB of 274, what
is the direction of each line?
AB = SW, BC = SE, CD = NE, DE = NW, EF = NW, FA = NW
4. Provide the back azimuth for the following azimuths:
BA of 23212’07” = 5212’07”
BA of 15652’17” = 2307’43”
BA of 3132’42” = 11132’42”
5. Convert the following azimuths to bearings:
25143’52” = S7143’52”W
11132’59” = S6827’01”E
33632’52” = N2327’08”W
6. Given two successive azimuths of a traverse 6921’ followed by 22011’,
what is the counterclockwise interior angle between them?
7. Given two successive bearings of a traverse N4135’E followed by
N8736’E, what is the interior angle 133.59
4135’+ (180-8736’) = 13359’
8. A 4410’ line bears N6811’07E. What is the latitude and departure of the
line?
9. A 956’ line bears S3253’42”W. What is the latitude and departure of the
line?
Latitude = -802.7220’
Departure = -519.2050’
10. A 1436.32’ line has an azimuth of 17852’13”. What is the latitude and
departure of the line?
Latitude = -1435.7110’
Departure = 28.3120’
11. A 1233.45’ line has an azimuth of 12324’. What is the latitude and
departure of the line?
Latitude = -678.9900
Departure = 1029.7430
