A woman stands between a vertical mirror 1/2 meter tall and a distant tree whose height is H. She is 1.0 meter from the mirror, and the tree is 15.0 meter from the mirror. If she sees the tree just fill the mirror, find how tall is the tree? [Hint: The tree is behind her, and rays from its top and bottom get to her eye.]
