An escalator in a department store is to carry people a vertical distance of 90 feet between floors. How long is the escalator if it makes an angle of 30° with the ground? answer in feet ...?
There are several information's of immense importance already given in the question. Based on those given information's, the answer can be easily deduced. Vertical distance between the floors = 90 feet Angle of the escalator with the ground = 30 degrees Let us assume the length of the escalator = x feet Then Sin (30) = 90/x 0.5 = 90/x x = 90/0.5 = 180 feet
I hope the procedure is clear enough for you to understand and this is the answer that has come to your desired help.
