\n" ); document.write( "you can call the legs \"x\" and \"x+%2B+2\"
\n" ); document.write( "By the Pythagorean theorem:
\n" ); document.write( "\"x%5E2+%2B+%28x%2B2%29%5E2+=+10%5E2\"
\n" ); document.write( "\"x%5E2+%2B+x%5E2+%2B+4x+%2B+4+=+10%5E2\"
\n" ); document.write( "\"2x%5E2+%2B+4x+%2B+4+=+100\"
\n" ); document.write( "\"x%5E2+%2B+2x+%2B+2+=+50\"
\n" ); document.write( "\"x%5E2+%2B+2x+=+48\"
\n" ); document.write( "Complete the square:
\n" ); document.write( "\"x%5E2+%2B+2x+%2B+%282%2F2%29%5E2+=+48+%2B+%282%2F2%29%5E2\"
\n" ); document.write( "\"%28x+%2B+1%29%5E2+=+49\"
\n" ); document.write( "\"%28x+%2B+1%29%5E2+=+7%5E2\"
\n" ); document.write( "\"x+%2B+1+=+7\"
\n" ); document.write( "\"x+=+6\"
\n" ); document.write( "\"x%2B2+=+8\"
\n" ); document.write( "The legs are 6 ft and 8 ft
\n" ); document.write( "check:
\n" ); document.write( "\"6%5E2+%2B+8%5E2+=+10%5E2\"
\n" ); document.write( "\"36+%2B+64+=+100\"
\n" ); document.write( "\"100+=+100\"
\n" ); document.write( "OK
\n" ); document.write( "(2)
\n" ); document.write( "Call the unknown leg \"x\"
\n" ); document.write( "\"h+=+x+%2B+1\"
\n" ); document.write( "the other leg is \"5\"
\n" ); document.write( "\"%28x%2B1%29%5E2+=+5%5E2+%2B+x%5E2\"
\n" ); document.write( "\"x%5E2+%2B+2x+%2B+1+=+5%5E2+%2B+x%5E2\"
\n" ); document.write( "\"2x+%2B+1+=+25\"
\n" ); document.write( "\"2x+=+25+-+1\"
\n" ); document.write( "\"2x+=+24\"
\n" ); document.write( "\"x+=+12\"
\n" ); document.write( "\"x%2B1+=+13\"
\n" ); document.write( "The hypotenuse is 13 and the other leg is 12
\n" ); document.write( "check:
\n" ); document.write( "\"13%5E2+=+12%5E2+%2B+5%5E2\"
\n" ); document.write( "\"169+=+144+%2B+25\"
\n" ); document.write( "\"169+=+169\"
\n" ); document.write( "OK
\n" ); document.write( "
\n" );
