Sketch a diagram of the situation. What is the height of the escalator? feet As a 12-foot ladder leans against a building, it makes a 58 represent the situation. How far is the bottom of the ladder from the base of the building? ≈ 6.4 feet ≈ 10.2 feet ≈22.6 feet ≈19.2 A flagpole has a shadow that is 25 feet long. The angle of elevation from the end of the shadow to the top of the flagpole is 50
