I'm sorry to hear about your mother. Mathematics isn't very important compared to something like that. Fletch Sent from my iPad On Aug 29, 2012, at 7:26 PM, Chuck Hards <chuck.hards@gmail.com> wrote:
Thanks, professor!
My mom passed-on on Monday and I'm not feeling too charitable right now, or even sober enough to care. I appreciate your reply, Fletcher. I knew you'd know the shortcut.

You dont even need a protractor. Just calculate 20% of 90.
Go to public grade school in Utah, did you? On Aug 29, 2012 3:30 PM, "D P Pierce" <starsbirdsglyphs@gmail.com> wrote:
Seth, About what degree angle would 20% be? I think I remember a 20% grade means that in a 100 feet of horizontal travel the grade increases or decreases 20 feet. That would mean a 100% grade would be a 45 degree angle. I think a 20% grade would be a lot less than a 20 degree angle. I've forgotten all of my trigonometry or I could calculate it myself.
