Rita wants to measure the height of a tree. She sights the top of the tree, using a mirror that is lying flat on the ground. The mirror is 32ft from the tree, and Rita is standing 6.2ft from the mirror, as shown in the figure. Her eyes are 6ft

above the ground. How tall is the tree? Round your answer to the nearest foot. (The figure is not drawn to scale.)
