If the Circumcenter of the triangle formed by the points \(A(a, 3), B(b, 5)\) and \(C(a, b)\) is \((1,1)\), then out of all the possible coordinates of \(\mathrm{C}\) the sum of the absolute values of the distinct coordinates of \(\mathrm{C}\) is
- A 8
- B 9
- C 12
- D 4
Answer & Solution
Correct Answer
(B) 9
Step-by-step Solution
Detailed explanation
\(\because \mathrm{OP} \perp \mathrm{AC}\) \(\Rightarrow 12=(\mathrm{a}-\mathrm{b})(\mathrm{a}+\mathrm{b}-2)\) ...(i) Putting the value of \(b=-1\) and \(b=3\) in equation (i) we get coordinate of \(\mathrm{C}\) are \((5,3),(-3,3)(5,-1)\) and \((-3,-1)\) Now sum of the absolutes…
