Problem
An architect is building a structure that will place vertical pillars at the vertices of regular hexagon 
, which is lying horizontally on the ground. The six pillars will hold up a flat solar panel that will not be parallel to the ground. The heights of pillars at 
, 
, and 
are 
, 
, and 
meters, respectively. What is the height, in meters, of the pillar at 
?
