A child’s kite is on top of a straight pine tree. A ladder is placed against the tree and touches the kite. The ladder forms a 45degree angle with the flat ground. The base of the tree is 9 feet away from the base of the ladder. With only this information, how can you determine the height of the tree?

A diagram of this problem is a right isosles triangle. The right angle is where the tree touches the ground and the two 45 degree angles are where the kite hits the top of the tree and where the ladder hits the ground. The legs of an isosles triangle are equal. The tree is one of the legs and is 9 feet tall.
Can you go from there to get answer?
