For no. 1 only: A trigonometric leveling conducted by Jereza Surveying Company, the two points A and B of a certain rough terrain are each distance 2000 m. from a third point C, from which the measured vertical angles to A is 3°30' and to B is 1030'. Elevation at C is known to be 342.60 m. above sea level. Point C is in between A and B. 1. Compute the difference in elevation (in m.) between A and B considering the effect of the earth's curvature and refraction. (Final answer should be rounded-off to two decimal places). 2. Compute the difference in elevation (in m.) between B and C. (Final answer should be rounded-off to two decimal places). 3. Compute the elevation of A (in m.). (Final answer should be rounded-off to two decimal places).
