You can put this solution on YOUR website!
The lengths of the sides of a right triangle follow the equation \"a%5E2+%2B+b%5E2+=+c%5E2\", where a and b are the length of the legs/sides and c is the length of the hypotenuse.
\n" ); document.write( "Plug the stated lengths of the sides into the equation as the values of a and b, then solve for c.
\n" ); document.write( "==> \"a%5E2+%2B+b%5E2+=+c%5E2\"
\n" ); document.write( "==> \"%288%29%5E2+%2B+%2815%29%5E2+=+c%5E2\"
\n" ); document.write( "==> \"64+%2B+225+=+c%5E2\"
\n" ); document.write( "==> \"289+=+c%5E2\"
\n" ); document.write( "==> Square root both sides: \"sqrt%28289%29+=+sqrt%28c%5E2%29\"
\n" ); document.write( "==> Simplify: \"17+=+c\"
\n" ); document.write( "***Therefore, the length of the hypotenuse is C. 17 cm
