The ratio of the sides of a 30-60-90 triangle are known to be 1:2:sqrt(3).
\n" ); document.write( "The shorter leg is 10 cm.
\n" ); document.write( "Therefore, the hypotenuse is 2*10 = 20 cm.
\n" ); document.write( ".
\n" ); document.write( "Check the solution with the Pythagorean Theorem.
\n" ); document.write( "c^2 = a^2 + b^2
\n" ); document.write( "20^2 = 10^2 + (10*sqrt(3))^2
\n" ); document.write( "400 = 400
\n" ); document.write( "True.
\n" ); document.write( ".
\n" ); document.write( "The hypotenuse of the triangle is 20 cm.
\n" ); document.write( ".
\n" ); document.write( "Done.
\n" ); document.write( "
