This is a Pythagorean question involving
\n" ); document.write( "the solving of the length of the hypotenuse
\n" ); document.write( "represented by the ladder.
\n" ); document.write( "The vertical side of the triangle is the
\n" ); document.write( "wall and measures 12m.
\n" ); document.write( "The base side of the triangle is the
\n" ); document.write( "distance the foot of the ladder is away from
\n" ); document.write( "the wall.
\n" ); document.write( "Vertical side^2 + Base side^2 = Hypotenuse^2
\n" ); document.write( "12^2 + 5^2 + Hypotenuse^2
\n" ); document.write( "Hypotenuse = $\"sqrt%2812%5E2+%2B+5%5E2%29\"$
\n" ); document.write( "Hypotenuse = $\"sqrt%28169%29\"$
\n" ); document.write( "Hyoptenuse = 13
\n" ); document.write( "Therefore the length of the ladder
\n" ); document.write( "= 13 metres.
