Question 1115648
Right triangle, height of 12 feet and angle opposite this height is the given 60 degrees.  Hypotenuse is the path of travel from bottom of belt to top of belt.


{{{12/h=sin(60)}}}


{{{h/12=1/sin(60)}}}


{{{h=12/sin(60)}}}


{{{h=12(2/sqrt(3))}}}


{{{h=12*2*sqrt(3)/3}}}


{{{highlight(h=8*sqrt(3))}}}
