Best ResponseYou've already chosen the best response.1we can obtain value \(\tan 15\) from \[\tan(4530)=\frac{\tan45\tan30}{1+\tan45\tan30} = \frac{1\frac{1}{\sqrt{3}}}{1+\frac{1}{\sqrt{3}}}=\frac{\sqrt{3}1}{\sqrt{3}+1}=2\sqrt{3}\] now, to obtain \(\tan7.5\) we use \[\tan15=\frac{2\tan7.5}{1\tan^27.5}\] which can solve by Quadratic formula
