Ladder makes a right triangle with the wall and ground. The hypotenuse = length of the ladder = 10 ft\r
\n" ); document.write( "\n" ); document.write( "Let the height be h
\n" ); document.write( "By Pythagorean theorem \r
\n" ); document.write( "\n" ); document.write( "10^2 = 3^2 + h^2\r
\n" ); document.write( "\n" ); document.write( "h^2 = 10^2 - 3^2 = 100 - 9 = 91
\n" ); document.write( "h = sqrt( 91) = 9.54 ft\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
