Posted: Tue Mar 26, 2013 11:11 amAnother question from INV A test. I am not getting the correct answer on #13. Anyone have any suggestions?
#13. Roland Upp built a skateboard ramp that is 20 feet long and the end of the ramp is 3 feet from the ground. What is the angle of inclination of the ramp? (nearest second)
The answer is supposed to be 8 degrees 37 minutes and 37 seconds. I keep getting 8 degrees 31 minutes and 51 seconds.
