In \(\triangle \mathrm{ABC}, \frac{\mathrm{a}}{\mathrm{s}-\mathrm{a}}+\frac{\mathrm{b}}{\mathrm{s}-\mathrm{b}}+\frac{\mathrm{c}}{\mathrm{s}-\mathrm{c}}=\)
- A \(\frac{4 \mathrm{R}}{\mathrm{r}}-1\)
- B \(\frac{\mathrm{R}}{\mathrm{r}}-3\)
- C \(\frac{2 \mathrm{R}}{\mathrm{r}}-1\)
- D \(\frac{4 R}{r}-2\)
Answer & Solution
Correct Answer
(D) \(\frac{4 R}{r}-2\)
Step-by-step Solution
Detailed explanation
\(\begin{aligned} & \text { } \frac{a}{s-a}+\frac{b}{s-b}+\frac{c}{s-c} \\ & =\frac{a(s-b)(s-c)+b(s-a)(s-c)+c(s-a)(s-b)}{(s-a)(s-b)(s-c)}\end{aligned}\)…
