Best ResponseYou've already chosen the best response.1we have this: \[\Large \tan 90 = \tan \left( {28 + 62} \right) = \frac{{\tan 28 + \tan 62}}{{1  \tan 28\tan 62}}\]

Best ResponseYou've already chosen the best response.1now, since tan90= infinity, we have to request that: \[\Large 1  \tan 28\tan 62 = 0\]
