Question 79134
Basically what we have is a right triangle with a height (opposite side) of 33,000 ft and a base (adjacant side) of 22 mi.  YOU ARE RIGHT!!!!!  We must either deal in miles or feet.  So let's deal in feet:

22 mi=22*5280 ft =116,160 ft

Slope =tangent of included angle which equals opposite side divided by the adjacant side.  So we have

Slope=TAN (theta)=33,000/116,160=0.28409=0.28

Hope this helps-----ptaylor
