In a triangle \(A B C, \frac{a\left(m_1+r_2 m_3\right)}{n_1-r+r_2+r_3}=\)
- A \(\sqrt{r_1 r_2 r_3}\)
- B \(r_1 r_2+r_2 r_3+r_3 r_1\)
- C \(2(R+r)\)
- D \(2+\frac{r}{2 R}\)
Answer & Solution
Correct Answer
(A) \(\sqrt{r_1 r_2 r_3}\)
Step-by-step Solution
Detailed explanation
\(r_1-r+r_2+r_3=\frac{\Delta}{s-a}-\frac{\Delta}{s}+\frac{\Delta}{s-b}+\frac{\Delta}{s-c}\)…
