Hi
\n" ); document.write( "*In questions regarding right triangles, the Pythagorean Theorem can be useful to help us solve the problem:

\n" ); document.write( "Pythagorean Theorem
\n" ); document.write( "\"a%5E2+%2B+b%5E2+=+c%5E2\" where a and b are the two sides that meet at the right angle and c (hypotenuse) is the side opposite the right angle.

\n" ); document.write( "first question
\n" ); document.write( "\"80%5E2+%2B+w%5E2+=+100%5E2\"
