You can put this solution on YOUR website!
You can solve using Pythagoras theorem
\n" ); document.write( "Hypotenuse = 12
\n" ); document.write( "distance on ground = 9
\n" ); document.write( "Height of ramp =h\r
\n" ); document.write( "\n" ); document.write( "12^2-9^2= h^2
\n" ); document.write( "144-81=h^2
\n" ); document.write( "h= sqrt(63)
\n" ); document.write( "h= sqrt(9*7)
\n" ); document.write( "h=3sqrt(7)
\n" ); document.write( "
\n" );
