answer number 3 onlytopic invisibility. 1. Two hills are in 120km apart the higher is at the 325.7 m and the lower hill at elevation of72m. Find the minimum height of tower on top of the higher hill that can be seen from thelower hill?2. Determine how far out to sea a boat will be when a light on its mast is 22m above the waterdisappear from the sight of a man on shore whose eye level is 1,7m above sea water. Disregardthe effects of tides and waves.3. The top of the mast signal 1750m away was sighted through a transit with recorded verticalangle of 4° 55'. The height of the mast is 5.5m and the height of the instrument above the pointthe base of the signal 'B' is 167.23m, compute theelevation of the point under the transit 'A’ with allowance due for curvature and refraction usingwhere it was set up is 1.15m. the elevationh= 0.067k24. Find the equal height of towers at triangulation stations A and C so that line AC will clear theelevated ground between A and C by 6m. with the instrument set at point B, the observedvertical angle to ground station A is 0°55' and the vertical angle to groundstation C is 0•48'.Elevation of A is 237m. Distance AB is 10km and distance of BC is 8.7km. Yhe instrument set-upat B is 2.7m above the ground. Use hcr= 0.067k?
