Earl's school is 64 feet tall. Earl walks 50 feet away from the school and uses an inclinometer to measure the angle of elevation from the ground at his feet to the roof of the school. It measures 52°. Then, Earl walks 50 feet away from the base of a tree. He uses the inclinometer again to measure the angle of elevation to the top of the tree, which is 52°. Which statement best describes the height of the tree?

• The height of the tree is 64 feet because the two triangles are congruent by AAS.

• The height of the tree is 64 feet because the two triangles are congruent by ASA.

• The height of the tree is 40 feet because it is the leg of a right triangle with other sides that measure 50 feet and 64 feet.

• The height of the tree is 81 feet because it is the hypotenuse of a right triangle with legs that measure 50 feet and 64 feet.
