You've got a right triangle therefore you use the Pythagorean theorem to find your missing side.

\n" ); document.write( "c^2 = a^2 + b^2\r
\n" ); document.write( "\n" ); document.write( "4^2 + 12^2 = c^2
\n" ); document.write( "16 + 144 = c^2
\n" ); document.write( "160 = c^2
\n" ); document.write( "4 square root of 10 cm is your answer =)
