A) \[\frac{5\sqrt{3}}{2}\]
B) \[5\sqrt{\frac{3}{2}}\]
C) \[5\sqrt{\frac{2}{3}}\]
D) None of these
Correct Answer: B
Solution :
We have \[\tan \alpha =\frac{5}{x}\] and \[\tan 2\alpha =\frac{30}{x}\] \[\therefore \] \[\tan 2\alpha =\frac{30}{5\cot \alpha }\Rightarrow \tan 2\alpha =6\tan \alpha \]You need to login to perform this action.
