Answer & Solution

Correct Answer

(C) \(\left(\frac{5}{2}, \frac{-1}{2}\right), \sqrt{\frac{13}{2}}\)

Step-by-step Solution

Detailed explanation

We have, Equation of sides of triangle are \(2 x+3 y=10 \Rightarrow y=x \Rightarrow y=0\) Solving we get \(A(2,2), B(0,0), C(5,0)\) Let equation of circle formed by triangle is \(x^2+y^2+2 g x+2 f y+c=0\) put \((0,0) \Rightarrow c=0\) put \((5,0)\)…
