probably 66% grade to start with.
which would put it at about 33.5 degrees.

percent grade is equal to rise over 100 ft horizontal distance. so a 66% grade climbs 66 ft over 100 ft.
to find the angle theta, take the inverse tangent of .66
tan^-1(.66) = 33.424
edit: the picture looks much prettier when i made it. Damn board messes it all up
