The ratio of the run to the rise is the cotangent of the angle, so
run/rise = cot[angle]
run = rise*cot[angle]
run = 21" * cot[9 degrees]
run = 21" * 6.31375...
run = 132.59".
Of course, the actual length of the ramp will be slightly longer
rampLength = 21*cosecant[9 degrees]
= 21*6.39245...
= 134.24"

with a run=21"*cot[9 degrees], on the cotangent solution how did you get 6.31375 ? thanks for the info, I appreciate your help time and help.
