the hypotenuse of an isosceles right triangle is 18 centimeters. find the length of a side.
\n" ); document.write( ":
\n" ); document.write( "Let x = the two equal sides a & b
\n" ); document.write( "x^2 + x^2 = 18^2
\n" ); document.write( "2x^2 = 324
\n" ); document.write( "x^2 = $\"324%2F2\"$
\n" ); document.write( "x^2 = 162
\n" ); document.write( "x = $\"sqrt%28162%29\"$
\n" ); document.write( "x ~ 12.728
