TS EAMCET · Maths · Properties of Triangles
In a triangle ABC, if \(r_1=4, r_2=8\) and \(r_3=24\), then \(a: b: c=\)
- A \(4: 7: 9\)
- B \(2: 3: 5\)
- C \(1: 2: 6\)
- D \(6: 2: 1\)
Answer & Solution
Correct Answer
(A) \(4: 7: 9\)
Step-by-step Solution
Detailed explanation
\( \frac{1}{r} = \frac{1}{r_1} + \frac{1}{r_2} + \frac{1}{r_3} = \frac{1}{4} + \frac{1}{8} + \frac{1}{24} = \frac{6+3+1}{24} = \frac{10}{24} = \frac{5}{12} \) \( s = \Delta \left(\frac{5}{12}\right) \)…
