http://www.easycalculation.com/area/triangle-angles.phpHere are the numbers. The trail is 760' long and has an elevation gain of 225'. Thanks.
The answer is 16.49 degrees

You are correct. A 100% grade is an angle of 45°.Originally Posted by rickboudrie
So if the rise was 760 feet over that same distance, the grade would be 100%?
Seems to me that the grade would be just 45 degrees.

You beat me to it!!! Here as well.
Discussion is percent of slope versus angle of slope....

Thanks 4eyedbuzzard!
Yet another day I leaned something here on WhiteBlaze!
Hence force I will forever be describing my hikes in terms of percent grade, rather than in terms of an angle.
It definitely sounds a whole lot scarier to describe the last section of Trail before the Tableland as a 100% grade, rather than just a 45 degree climb!
Another problem here is that trail length is generally the hypotenuse, not the adjacent leg or "run" in a grade/angle equation.

Actually, 17.22 degrees; the hyp. is the trail
I get your angle, Groucho.
Wow, and here I've been telling my high school daughter that there is only one correct answer to choose for the math SAT!
This is also a great case study that not everything you read on the Internet is true!
