Use Pythagorean theorem:
\n" ); document.write( "a^2 + b^2 = c^2
\n" ); document.write( "Let x be length of other leg, then hypotenuse is (x+4).
\n" ); document.write( " $\"x%5E2+%2B+8%5E2+=+%28x%2B4%29%5E2\"$
\n" ); document.write( " $\"x%5E2+%2B+64+=+x%5E2+%2B+8x+%2B+16\"$
\n" ); document.write( " $\"48+=+8x\"$
\n" ); document.write( " $\"6+=+x\"$
\n" ); document.write( "Therefore, the other leg is 6 and the hypotenuse is 10.
\n" ); document.write( " \n" ); document.write( "
