Algebra.Com's Answer #841626 by greenestamps(13215) You can put this solution on YOUR website! \n" ); document.write( "Don't use \"\\" -- it might have a special meaning in some area(s) of mathematics. \n" ); document.write( "I assume the side lengths are p/sqrt(6), q/sqrt(3), and p/sqrt(2). \n" ); document.write( "The squares of the side lengths are then p^2/6, q^2/3, and p^2/2. \n" ); document.write( "On first glance, with the denominators 6, 3, and 2, I immediately see that, if p and q are both equal to the same number x, then I have x^2/6+x^2/3=x^2/2, which is true for all values of x. \n" ); document.write( "So the problem has an infinite number of solutions in which p=q. \n" ); document.write( "But there might be other solutions hiding somewhere, so lets' look at the problem more closely. \n" ); document.write( "We know that p/sqrt(2) is greater than p/sqrt(6); but q/sqrt(3) could be less than or greater than p/sqrt(2). So there are two cases to consider: the longest side (hypotenuse) can be either p/sqrt(2) or q/sqrt(3). \n" ); document.write( "Case 1: the hypotenuse is p/sqrt(2) \n" ); document.write( "(Note this is the case discussed informally above.) \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Case 2: The hypotenuse is q/sqrt(3) \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "This case also has an infinite number of solutions, where p is any number x and q is x*sqrt(2). \n" ); document.write( "ANSWER: \n" ); document.write( "p = any number; \n" ); document.write( "q = p OR q=p*sqrt(2) \n" ); document.write( " \n" ); document.write( " |
