For a project in her Geometry class, Ashley uses a mirror on the ground to measure the height of her school building. She walks a distance of 8.45 meters from her school, then places a mirror on flat on the ground, marked with an X at the center.

Her partner measures the distance from her eyes to the ground to be 1.15 meters. How tall is the school? Round your answer to the nearest hundredth of a meter.
