The vertical rise of escalator is 623.49 inch.
In one feet [tex]= 12 inch[/tex]
200 feet [tex]=200*12=2400inch[/tex]
So that, 200 feet and 9 inch [tex]=2409inch[/tex]
Let us consider that vertical rise of escalator is x .
A diagram is attached below,
Apply Sine of angle.
[tex]sin(15)=\frac{x}{2409}\\\\x=2409*sin(15)\\\\x=2409*0.26\\\\x=623.49 inch[/tex]
Thus, the vertical rise of escalator is 623.49 inch.
