To estimate the height of a​ tree, Tia and Felix walk away from the tree until the angle of sight with the top and bottom of the tree is a right angle. Let h represent the height of a​ person's eyes and d represent the distance away from the tree. Answer parts a to c below.
a. If the height of​ Tia's eyes is 1.6 m and her distance away from the tree is 2.5​ m, what is the height of the​ tree?
The height of the tree is about
