For a project in her Geometry class, Lauren uses a mirror on the ground to measure the height of her school's football goalpost. She walks a distance of 12.35 meters from
the goalpost, then places a mirror on flat on the ground, marked with an X at the
center. She then steps 2.85 meters to the other side of the mirror, until she can see
the top of the goalpost clearly marked in the X. Her partner measures the distance
from her eyes to the ground to be 1.35 meters. How tall is the goalpost? Round your
answer to the nearest hundredth of a meter.
