1. The problem statement, all variables and given/known data A 6.0 mile long section of railroad has an angle of inclination of 2.1 degrees. Find the change in elevation over the 6 miles. Give your answer in feet. 2. Relevant equations sine=opp/hyp 3. The attempt at a solution Sin 2.1=6/hyp h=6 mi/2.1sin h=163.7 mi=864336 ft. Seems off, but I'm not sure. I think I did something backwards, maybe? Let's try this: h=2.1sin/6 mi h=0.006 miles. h=32.25 ft. This seems further off.
