KINDLY DRAW THE REPRESENTATION WITH THE THREE HEELS Three hills A, B, and C are at elevations 135m, 146m, and 154m respectively above sea level. Distance AB is 3.9km while distance BC is 3.1km. a) Find the effect of curvature and refraction between A and B. b) Determine the effect of curvature and refraction between A and B. c) What would be the height of tower to be constructed at hill C so that the line of sight will clear hill B by 2.5m considering the effect of earth’s curvature and refraction?
