Pete is standing 2 feet away from a mirror on the ground. Pete is 5 feet tall and can just see the top of the tree in the mirror from where he is standing. The mirror is 8 feet away from the base of the tree. how tall is the tree?

Answer 1

What do you mean by "just see"?

Pete has to look up into the mirror, so he is not standing in the way.

If he looks way high into the mirror, the tree is way tall. If he looks just slightly up, the tree is not so tall.

What does he have to look past that blocks his view up to the top of the tree?
