rio is standing on top of a building and notices a turtle walking towards the building. He notices that the angle of depression from the top of the building to the turtle’s position is 48◦. The turtle then walks 120 feet closer to the building. Mario now notices that the angle of depression is now 68◦. Determine that the height of the building is exactly 120 tan 68◦ tan 48◦ h= tan68◦−tan48◦ ft.
