QUESTIONS AND PROBLEMS

What is the angular closure for the following interior field angles of traverse ABCDEF, measured with equal precision?

A$.87{54}^{\text{'}}{14}^{\text{'}\text{'}}$

B$.90{32}^{\text{'}}{45}^{\text{'}\text{'}}$

C$.102{43}^{\text{'}}{31}^{\text{'}\text{'}}$

D$.99{24}^{\text{'}}{34}^{\text{'}\text{'}}$

E$.156{01}^{\text{'}}{55}^{\text{'}\text{'}}$

F$.183{23}^{\text{'}}{01}^{\text{'}\text{'}}$

Using the angles in the previous problem, how much adjustment is needed for each angle?

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.

Provide the back azimuth for the following azimuths:

a$)232{12}^{\text{'}}{07}^{\text{'}\text{'}}$

b$)156{52}^{\text{'}}{17}^{\text{'}\text{'}}$

c$)31{32}^{\text{'}}{42}^{\text{'}\text{'}}$

Convert the following azimuths into bearings:

a$)251{43}^{\text{'}}{52}^{\text{'}\text{'}}$

b$)111{32}^{\text{'}}{59}^{\text{'}\text{'}}$

c$)336{32}^{\text{'}}{52}^{\text{'}\text{'}}$

Given two successive azimuths of a traverse $69{21}^{\text{'}}$ followed by $220{11}^{\text{'}},$ what is the counterclockwise interior angle between them?

Given two successive bearings of a traverse $N41{35}^{\text{'}}E$ followed by $N8736E,$ what is the interior angle between them?

A ${4410}^{\text{'}}$ line bears $N68{11}^{\text{'}}{07}^{\text{'}\text{'}}E.$ What is the latitude and departure of the line?

A ${956}^{\text{'}}$ line bears $S32{53}^{\text{'}}{42}^{\text{'}\text{'}}W.$ What is the latitude and departure of the line?

A ${1436\mathrm{.}32}^{\text{'}}$ line has an azimuth of $178{52}^{\text{'}}{13}^{\text{'}\text{'}}.$ What is the latitude and departure of the line?

A ${1233\mathrm{.}45}^{\text{'}}$ line has an azimuth of $123{24}^{\text{'}}.$ What is the latitude and departure of the line?

The closure in latitudes of a loop traverse is $N0\mathrm{.}0635$ feet; the closure in departures is $W0\mathrm{.}0512$ feet. What is the linear error of closure?
