1) Construction workers want to make an incline from the top of the cliff to the bottom to help get materials from the bottom of the cliff to the top. What is the angle of elevation needed if the length from the top of the cliff to the bottom of the ramp is 1500 feet and height of the cliff is 500 feet? media type="custom" key="9395530" 2)A person is sitting on a bench at a park looking up at a clock that is 12ft away. The distance from his eyes to the base of the clock is 8ft. Find the angle of elevation? media type="custom" key="9395532" 3) A balloon is flying 20 feet above the ground. The horizontal distance from the person to the balloon is 30 feet. If the person is 6 feet tall what is the angle of elevation from the person’s eyes to the balloon. media type="custom" key="9395534" 4) A cat is sitting on top of a tree and the owner needs to see how tall of a ladder they need in order to get the cat down.
