An equation of the sides of a right triangle can be written as \"a%5E2+%2B+b%5E2+=+c%5E2\", where a and b are the measures of the legs (the shorter sides) and c is the measure of the hypotenuse (diagonal/longest side). Assuming that your a and b are the legs of the right triangle, plug your values into the equation:\r
\n" ); document.write( "\n" ); document.write( "\"a%5E2+%2B+b%5E2+=+c%5E2\"
\n" ); document.write( "\"5%5E2+%2B+4%5E2+=+c%5E2\"
\n" ); document.write( "\"25+%2B+16+=+c%5E2\"
\n" ); document.write( "\"41+=+c%5E2\"\r
\n" ); document.write( "\n" ); document.write( "Next, square root both sides of the equation:\r
\n" ); document.write( "\n" ); document.write( "\"sqrt%2841%29+=+sqrt%28c%5E2%29\"
\n" ); document.write( "Since \"sqrt%28c%5E2%29\" is the same as c: \"sqrt%2841%29+=+c\"
\n" ); document.write( "\"sqrt%2841%29\" cannot be simplified.\r
\n" ); document.write( "\n" ); document.write( "Therefore, the length of the third side/c/hypotenuse of the right triangle is \"sqrt%2841%29\" meters.
\n" ); document.write( "
\n" );
