46 2:35 0.30 sE 4G 22 KB/s Point A is between points B and C. The distances of B and C from A are 2000m and 3000m, respectively. Measured from point A, the angle of elevation of point B is +18°30', while that on point C is +8°15'. Find the difference in elevations between B and C. Your answer A backsight of 3.265m is taken on a point 175 m from a level station and a foresight of 1.118m from the same station. Determine the difference in elevation between the two points, taking into account the combined effect of curvature and refraction. Your answer Two identical towers, A and B, are located on level ground and their bases have equal elevations above sea level. Determine the distance (in feet) between the two towers if a person standing on top of tower A can just see the top of tower B. His eyes on the level of top of tower A is 50 ft above the ground. Your answer By taking a sight across a lake 15 miles wide through a pair of binoculars, determine the height (in feet) of the shortest…

GIven the traverse below, determine the area of the traverse by triangle method generating from station B.
