Pythagorean theorem: \"a%5E2+%2B+b%5E2+=+c%5E2\", with c the hypotenuse.\r
\n" ); document.write( "\n" ); document.write( "\"a+=+c-10\"
\n" ); document.write( "\"b+=+c-+80\"\r
\n" ); document.write( "\n" ); document.write( "\"%28c-10%29%5E2+%2B+%28c-80%29%5E2+=+c%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"c%5E2+-+20c+%2B+100+%2B+c%5E2+-+160c+%2B+6400+=+c%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"c%5E2+-+180c+%2B+6500+=+0\"\r
\n" ); document.write( "\n" ); document.write( "\"%28c-50%29%28c-130%29+=+0\"\r
\n" ); document.write( "\n" ); document.write( "\"c-50=0\" or \"c-130=0\"
\n" ); document.write( "\"c=50\" or \"c=130\"\r
\n" ); document.write( "\n" ); document.write( "If \"c=50\", then \"a=c-10=40\" and \"b=c-80=-30\". We cannot have negative numbers for side length.\r
\n" ); document.write( "\n" ); document.write( "Thus:\r
\n" ); document.write( "\n" ); document.write( "\"c=130\"
\n" ); document.write( "\"a=120\"
\n" ); document.write( "\"b=50\"
\n" ); document.write( "
\n" );
