Q30: Trigonometric Leveling) Similar to Problem above, except the slope distance was 854.987 m, the zenith angle was 82° 13 45and the elevation of point P was 354.905 m above datum. What is the elevation of point Q? Q31: Trigonometric Levelingł In trigonometric leveling from point A to point B, the slope distance and zenith angle measured at A were 2504.897 m and 85° 08 54. At B these measurements were 2504.891 m and 94° 52 10respectively. If the instrument and rod target heights were equal, calculate the difference in elevation from A to B
