1. Trigonometric leveling-If the Rod height was 5.4 feet at the BS (elevation 4700.00), the zenith angle was 62°50'30", the slope distance was 450.00 feet. What is the height of the instrument? Then you turn to a FS and read a zenith angle of 90°12'59" and the slope distance is 380.00 feet, the Rod height was 6.3 feet at the FS, what is the elevation of the point at the FS?
2. The magnetic bearing of a boundary line was recorded as S 43°30'E in 1862. At that time and place, the magnetic declination was known to be 3°15'W. Determine the true azimuth and bearing for that line.
3. Describe parcels E & H using aliquot parts description and calculate the area of each in acres.
4. For the simple curve with an arc length of 1090.83 feet and a tangent of 606.81 feet, if the station of the PI is 24+57.00, what are the stations of the PC and the PT?
PC = ______________
PT = ______________
5. Given a vertical parabolic curve that has its PVI at station 16 + 63.64 and elevation at 2923.00. The grade of the back tangent is +6.39%, the grade of the forward tangent is -3.86%, and the curve length is 300 ft. What is the Station and Elevation of the turning point (high point)? What is the Elevation of Station 16+00?
