the ramp is the hypotenuse of a right triangle formed by the ramp, the ground, and the vertical rise\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the sine of the angle with the ground is (vertical rise)/(ramp or 5/30\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let x=angle ___ sin(x)=1/6
\n" ); document.write( "
