Question

The observed lengths of the sides (in feet) of a five-sided closed polygon traverse are as follows:

*A**B*ABAB = 201.74, *B**C*BCBC =
283.87, *C**D*CDCD = 470.37, *D**E*DEDE
= 330.33, and *E**A*EAEA = 379.78. (Note: Assume
units of feet for all distances.)

The preliminary azimuths obtained after balancing the angles are as follows:

*A**B*=218∘59′30′′AB=218∘59′30″ ,
*B**C*=147∘45′49′′BC=147∘45′49″ ,
*C**D*=75∘05′27′′CD=75∘05′27″ ,
*D**E*=336∘56′04′′DE=336∘56′04″ ,
*E**A*=266∘12′23′′EA=266∘12′23″ .

a) Computer the departures of the sides.(three sig figs)

b) computer the latitudes of the sides. (three sig figs)

c) linear misclosure. (three sig figs)

d) computer the relative precision. (three sig figs)

Answer #1

Lattitude = Length of line × cosine of bearing of same line

Departure = length of line × sine of bearing of same line

The lengths of the sides (in feet) of a five-sided closed
polygon traverse are as follows:
ABABAB = 204.74, BCBCBC = 263.87, CDCDCD = 462.37, DEDEDE =
312.33, and EAEAEA = 374.78. (Note: Assume units of feet for all
distances.)
The azimuths are as follows:
AB=218∘59′30′′AB=218∘59′30″, BC=147∘45′49′′BC=147∘45′49″,
CD=75∘05′27′′CD=75∘05′27″, DE=336∘56′04′′DE=336∘56′04″,
EA=266∘12′23′′EA=266∘12′23″.
A.)Compute the departures of the sides.
ABAB, BCBC, CDCD, DEDE, EAEA =
B.)Compute the latitudes of the sides.
ABAB, BCBC, CDCD, DEDE, EAEA =
C.)Compute the linear misclosure.
D.)Compute the...

A five-sided closed field traverse has the following distances
in feet: AB = 647.25; BC = 203.03; CD = 720.35; and DE = 610.24;
and EA = 285.13. The interior angles are as follows (measured as
angles to the right): A = 100º 45' 37"; B = 231º 23' 43"; C = 17º
12' 59"; D = 89º 03' 28"; and E = 101º 34' 24". The bearing of AB
is S 53º 04' 43" E. Determine the bearings of...

Researchers in a 2015 study by Flannery et al. sought to
estimate the effectiveness of the seasonal influenza vaccine in
preventing acute respiratory infection (ARI). A total of 507
subjects from Texas who showed symptoms of ARI were recruited for
this study. The data provided show the result of each subject's
test for influenza.

Your firm works in construction and buys ASTM A325M8S bolts in
very large numbers. You are interested in purchasing bolts from
different suppliers and have obtained and tested samples of 200
bolts from three suppliers: Allnutt, Boltzman, Coachers.You have
tested these in your new bolt testing machine, purchased after you
had discovered your old bolt testing machine was performing
erratically. (For the purposes of this question, you are safe to
assume that the new machine works perfectly and that its...
