Best ResponseYou've already chosen the best response.1\[\tan(2x) = \cot(90 + x 30) \implies (\tan(x30)) = \tan(x  \frac{\pi}{6})\] \[\implies \tan(2x) = \tan(x  \frac{\pi}{3})\]

Best ResponseYou've already chosen the best response.1General solution is given by: \[\tan ( \theta) = \tan(x)\] then: \[\theta = n \pi + x\]

Best ResponseYou've already chosen the best response.1so: \[2x = n \pi + ( x  \frac{\pi}{3} ) \implies x = n \pi + \frac{\pi}{3}\]

Best ResponseYou've already chosen the best response.1\[\tan(2x) = \cot(x60) \implies \cot(90  (x + 150)) \implies \tan(x + 150)\] \[\tan(2x) = \tan(x + 150)\]
