The longest side of a triangle is 11 inches, the second side is 8 inches shorter than that. Find the 3rd side.
\n" ); document.write( ".
\n" ); document.write( "You must apply Pythagorean theorem.
\n" ); document.write( "The longest side (11 inches) is the hypothenuse.
\n" ); document.write( "The second side (since it is 8 inches shorter) is 3 inches.
\n" ); document.write( ".
\n" ); document.write( "Therefore:
\n" ); document.write( "Let x = third side
\n" ); document.write( ".
\n" ); document.write( "Then we have:
\n" ); document.write( "x^2 + 3^2 = 11^2
\n" ); document.write( "x^2 + 9 = 121
\n" ); document.write( "x^2 = 112
\n" ); document.write( "x = {-10.583, 10.583}
\n" ); document.write( ".
\n" ); document.write( "Tossing out the negative answer:
\n" ); document.write( "3rd side is 10.583 inches
\n" ); document.write( "
\n" ); document.write( "
