Question

An escalator in the subway station has a vertical rise of 195 ft. and rises at angle of 10.4 degrees. How long is the escalator? Round to the nearest foot.

Answer 1

about 1,062 feet

Explanation:

Set your calculator to degree mode.

The figure is omitted--please sketch it to confirm my answer.

`\tan(10.4) = (195)/(l)`

`l = (195)/( \tan(10.4) ) = 1062.47`
