(30 POINTS) Elliott is standing at the top of a store escalator that leads to the ground floor below. The angle of depression from the top of the escalator to the floor is 36.84°, and the escalator is 15 feet long. How far is the top of the escalator from the ground floor? Round your answer to the nearest foot. 9 feet 12 feet 20 feet 36 feet Also i should add that i had this question before, but i got it incorrect because i was supposed to find the angle complementary to 36.84. The first time i got this question, i used cos 36.84 = x + 15.
