Three Hills A, B and C has elevations of 660m, 625m, and 600m respectively. B is in between A and C, and is 10km from A and 12 km from C. (30 points) a. Considering the effect of curvature and refraction correction, what is the clearance or obstruction of the line of sight at B considering that C is visible from A. b. If a 5 m tower is erected on top of B, what would be the height of equal towers to be erected at A and C in order that A, B and C will be intervisible.
