#1**0 **

*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 **2.87 ^{o}**.
