the ladder forms a right triangle with the wall.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the vertical length up the wall is one leg.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the horizontal length from the wall to the ladder is the other leg.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the length of the ladder is the hypotenuse.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in a right triangle, c^2 = a^2 + b^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "c is the hypotenuse
\n" ); document.write( "a is one leg
\n" ); document.write( "b is the other leg.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "c^2 = a^2 + b^2 becomes c^2 = 5^2 + 1^2 = 25 + 1 = 26\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "c is equal to the square root of (26).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's the length of the ladder.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "square root of 26 is approximately equal to 5.099 meters rounded to 3 decimal places.\r
