sin(theta) = opposite/hypotenuse\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "sin(9) = h/18\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "18*sin(9) = h\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "h = 18*sin(9)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "h = 18*0.156434465040231\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "h = 2.81582037072416\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the height of the ramp is roughly 2.81582037072416 m which rounds to 2.8 meters\r
