The elevation of station Alpha is 680 m while that of Charlie is 620 m. In between stations Alpha and Charlie is station Bravo with elevation 645 m. The distance from Alpha to Bravo is 12 km and from Bravo to Charlie is 15 km. Assuming that station Bravo will obstruct the line of sight from station Alpha while observing station Charlie and a 4-m tower is constructed on top of station Bravo, find the height (in m) of equal towers at stations Alpha and Charlie in order that the three stations as observed from station Alpha will still be intervisible?
