Options:
A) $ 2ax $

C) $ 6ax $
D) $ 8ax $
Show Answer
Answer:
Correct Answer: B
Solution:
- $ A+C=B $ or $ \tan (A+C)=\tan B $
$ \Rightarrow $ $ \frac{\tan A+\tan C}{1-\tan A\tan C}=\tan B $
$ \Rightarrow $ $ \tan A+\tan C=\tan B-\tan A\tan B\tan C $
$ \Rightarrow $ $ \tan A\tan B\tan C=\tan B-\tan A-\tan C $
