The top of a tower signal at B, 2,000 m from A away was sighted through a transit with recorded vertical angle of 2°30'. The height of the mast is 12 m and the height of elevation of the transit above the point where it is set is 1.10 m. The elevation of the point under the transit A is 133.30 m. Considering the earth's curvature and refraction, find the most nearly gives the elevation (in m) of the base of the signal B?
