Answer & Solution

Correct Answer

(B) \(\frac{111}{8}\)

Step-by-step Solution

Detailed explanation

In a \(\triangle A B C\), it is given that \(\frac{\tan A}{2}=\frac{\tan B}{3}=\frac{\tan C}{4}=k \text { (Let) }\) \(\Rightarrow \quad \tan A=2 k, \tan B=3 k\) and \(\tan c=4 k\). Since in \(\triangle A B C\),…
