For a project in his Geometry class, Dominic uses a mirror on the ground to measure the height of his school's football goalpost. He walks a distance of 13.05 meters from
the goalpost, then places a mirror on flat on the ground, marked with an X at the
center. He then steps 7.25 meters to the other side of the mirror, until he can see the
top of the goalpost clearly marked in the X. His partner measures the distance from
his eyes to the ground to be 1.55 meters. How tall is the goalpost? Round your answer
to the nearest hundredth of a meter.
