1) How long should an escalator be if it is to make an angle of 33 degrees with the floor and carry people a vertical distance of 21 feet? 2) a road up a hill makes an angle of 5.1 degrees with the horizontal. if the road from the bottom of the hill to the top of the hill is 2.5 miles long, how high is the hill? 3) length of a rope. A 72.5 ft rope from the top of a circus tent pole is anchored to the ground 43.2 feet from the bottom of the pole. What angle does the rope make with the pole? Assume the pole is perpendicular.
