Question

solve #6

1. Balance the following interior angles (angles to the right) of five sided closed polygon traverse. If the azimuth of side AB is fixed at 218 59 30, calculate the azimuths of the remaining sides. A-132°47 06, B-108"46 18, C= 107。19 37, D-81.50 36. E-109.16 18, (Note: Line BC bears SE) Compute departure and latitudes, linear misclosure and relative precision for the traverse of problem above, if the length of the side (in feet) are as follows: AB 202.74; BC-283.87; CD-498.37; DE-320.33 and EA-380.78 (Note: Assume units of feet for all distances) 3. Using the compass (Bowditch) rule, adjust the departures and latitudes of the traverse in above problem. If the coordinates of the station A are X-20,000.00 ft and Y 15,000.00 ft, calculate (a) coordinates of the other stations (b) Lengths and azimuths of the lines BC and CD and, (c) the final adjusted angles at stations B and C. Balance the following interior angles-to-the-right for a polygon traverse to the nearest 1". Compute the azimuths assuming a fixed azimuth of 35°09'32" for line AB. A 57°00'34"; B-88°24'40"; C 126°37'20"; D-46 03'46"; E-221°5'30". (Note: Line BC bears NW.) 5. Determine departures and latitudes, linear misclosure, and relative precision for the traverse of Problem 4 if lengths of the sides (in meters) are as follows: AB-383.808; BC 360.209; CD-342.204; DE 336.210; and EA- 267.527. 6. Using the compass (Bowditch) rule adjust the departures and latitudes of the traverse in Problem 5. If the coordinates of station A are X - 310,630.892 m and Y 121,311.411 m, calculate (a) coordinates for the other stations and, from them, (b) the lengths and bearings of lines BC and EA, and (c) the final adjusted angles at B and D.
