The purpose of the station is todetermine the elevations of both points A and C which are located on thepeaks of the valley. Two vertical angles of +11°30’ and +13°15’ are madewith the scopes of the instrument to points A and C respectively.Preliminary survey suggests that points AB is measured with a horizontaldistance of 583m and points BC is measured with a horizontal distance of1,125m. Considering the earth’s curvature and atmospheric refraction,determine the elevation of both A and C if the elevation of the stationis 75m above sea level.arrow_forward
