PROBLEM 1 Given the following interior angles (angles-to-the-right) of a five-sided closedpolygon traverse and if the azimuth of side AB is fixed at 74°31'17", determine the adjusted azimuth of line EA.A =105°13'14"; B = 92°36'06"; C = 67°15'22"; D = 217°24'30"; E = 57°30"38". (Note: line BC bears NW.) THE ANSWER HERE IS Azimuth EA=149.300278 NEEDED TO ANSWER it is connected to problem 1: Compute the relative precision for the traverse of Problem 1 if the lengths of the sides (in feet) are as follows: AB = 2157.34; BC =1722.58;CD =1318.15; DE =1536.06; and EA =1785.58. (Note: Assume units of feet for all distances.) Round off the denominator to two decimal places.
24. If the surveyor is at Point A, and recorded the location of Line AB to be 200 degrees 35 minutes in WCB. The surveyor then recorded the location of Line AC to be 280 degrees 15 minutes in WCB. The length of AB is 530.68 meters and Length of AC is 275.45 meters. What is the angle of Line AB expressed in RB?
S62°30'E is incorrect. The answer should be N 62°30' W. Sketch the close traverse.
The observed lengths of the sides (in feet) of a five-sided closed polygon traverse are as follows: AB = 200.74, BC = 285.87, CD = 500.37, DE = 319.33, and EA = 380.78. (Note: Assume units of feet for all distances.) The preliminary azimuths obtained after balancing the angles are as follows: AB=138∘16′27" , BC=67∘02′46", CD=354∘22′24", DE=256∘13′01", EA=185∘29′20".
