**bobpursley**, Sunday, October 21, 2007 at 4:24pmLets take the 9 m out of the picture.

16^2=9^2 + E^2

so solve for the Escalator length, E.

Now, having E,

E^2=6^2+ H^2 where H is the horiontal displcement. Actually, looking at the equations, there is no reason to solve for E

16^2=9^2+6^2 + H^2

solve for H.

angle= arctan 6/H

I get close to 27 degrees.
