what is the slope of a pipe that 120 feet long and drops 6 feet     

 

If you visualize a right triangle with one side 6 feet and the hypotenuse 120 feet  

then the sine of the angle opposite the 6 foot side is 6/120, which equals 0.05.  

 

Then use your calculator, or the tables, to find the arcsine of that ratio.   

 

          sin–1(0.05) = 2.8659...  rounded to a reasonable number is 2.87.   

 

                                                                  The slope of the pipe is 2.87o.
