A five-sided closed traverse has the following interior angles: A 90 10 30 B = 115-41.30. 8 : 38:48:38: E 113°14 30 Determine the angular error and balance the angles by applying equal corrections to each angle. 4. Convert the follawina azimuths to bearing: (a) 141023 (b) 191948 (c) 12 13 20: (d) 351°10 (e) 280040: (f) 178°20. 5. Convert the following bearings to azimuths. la, N 21°20'W; (b) N 85°38·E; (e) N 60°06 W (f) s 8°10'E. (c) S 7902 2.E; (d) S 2016'1: 6. An open traverse that runs from A to H has the following deflection angles: G 10°15'1 If the bearing of AB is N 20°30 E, compute the bearings of the remain

Explanation / Answer

2.)

As we know that sum of interior angles of 5 sided closed traverse is 540 degrees

Sum of interior angles = 540

A+B+C+D+E = 540

427o15' + E = 540o

E = 112o 45'

3.)

Angular error = Actual interior angle of closed traverse - Calculated sum of interior angles

= 540o - (90o10'30"+ 115o 41'30"+120o10'30"+100o42'30"+113o14'30")

= 0o0'30"

As error is distributed equally thus correction of + 0o0' 6" is applied to each angle.

A = 90o10'36"

B = 115o 41'36"

C = 120o10'36"

D = 100o42'36"

E = 113o14'36"
