The observed magnetic bearings of a closed compass traverse are as follows: AB, Forward = N55 "30'E, Back = S55 "45W: BC, Forward = S58 "40'E, Back = N58 "30'W; CD, Forward = S14°30'E, Back = N14 °00'W; DE, Forward = 577 °10'W, Back = N77 °10'E; and EA, Forward = N40 °20'W, Back = S40 °15'E. Determine the following: a. Misclosure of the given traverse b. Adjusted interior angle of station C C. adjusted forward bearing of line CD
The constants K and C for a certain instrument were 100 and 0 respectively. The ground makes a uniform slope of 12% from point A to point B.With the instrument at A and staff at B, readings were taken but due to obstruction in the line of sight, only the upper reading was recorded to be 1.915m. If the vertical angle of the instrument was 6 degrees and 45minutes and height of instrument above A was 1.82 m. determinethe horizontal distance between A and B.
The interior angles of a five-sided traverse are as follows: A= 117°30' B=96°32' C=142°54' D=132°18' . The angle at E is not measured. What is the deflection angle at station D?

USE OF STADIA REDUCTION TABLES. From an instrument station a backsight, was made on a turning point and the following data were obtained: 9. upper stadia hair reading = 1.745m rod reading = 1.495m lower stadia hair reading = 1.245m stadia constant = 0.381m stadia interval factor = 95.5 observed vertical angle = -14°34' height of instrument aboye occupied station = 1.495m elevation of turning point = 463.24m Determine the elevation of the instrument station using values taken from stadia reduction tables.
An Instrument was set-up between points A and B which was 640m apart. The distance of the Instrument from A is 20m more than thrice the distance of the Instrument from B. When a sight was taken from the staff at A, only upper and middle staff reading was recorded as 3.247m and 2.821m respectively. While that on staff at B, upper and lower staff reading was taken as 1.286m and 0.812m respectively. Determine the following: 1. Stadia Constant. 2. Stadia Interval factor. 3. The slope of Line AB.
