Answer:
[tex]l=1085ft[/tex]
Explanation:
Since the answer is supposed to be feet convert the inches to feet
[tex]195+\frac{9.5}{12}=195.79ft[/tex]
The angle of rise is at the lower floor,so the vertical rise represents the opposite side of a right triangle.The length of the escalator is then hypotenuse of triangle
[tex]Sin(10.4)=\frac{195.79}{l}\\lSin(10.4)=195.79\\l=\frac{195.79}{Sin(10.4)}\\l=\frac{195.79}{0.18} \\l=1084.7ft\\round-it\\l=1085ft[/tex]
