You are given the map of Calakmul, a Maya archaeological site in the Mexican state of Campeche. On the main square (Gran Plaza) there are several buildings; in particular, building VI (Estructura VI) and building IV (Estructura IV). The latter is the complex of three temple towers.
It is known that if one looks from building VI to building IV, on the days of equinoxes and solstices, the rising Sun touches the tops of the respective towers (marked). The latitude of Calakmul is 18° North.
Estimate the height of the towers relative to the observation point. Consider the Sun as a point source
