It is desired to sight from Apayao Hill (Elev. = 4,135.63 m) to Ifugao Hill (Elev. = 4,153.92 m), 6.94 km away. Benguet Hill (Elev. = 4,145.68 m), 3.92 km away, obstructs the line of sight. If towers of identical heights are to be constructed at Apayao Hill and Ifugao Hill, so that the line of sight will clear the ground at Benguet Hill by 2.50 m, what is the minimum height of either of the tower?

Highway Surveys and Location

Surveying is an operation in the civil engineering domain that requires collecting and identifying data regarding an area of land and topography. The data that is collected can be helped to plan and undertake the construction process. Civil engineers perform surveys to gather three-dimensional information regarding a particular area. Engineers specify several points on the surface of the earth and relationship between points, and the distance and angles between the points are evaluated. The data from this evaluation guides in drawing plans regarding buildings and structures.
