\(A B C\) is a triangle, \(G\) is the centroid, \(D\) is the mid-point of \(B C\). If \(A=(2,3)\) and \(G=(7,5)\), then the point \(D\) is
- A \(\left(\frac{19}{2}, 6\right)\)
- B \(\left(\frac{9}{2}, 4\right)\)
- C \(\left(8, \frac{13}{2}\right)\)
- D \(\left(\frac{11}{2}, \frac{11}{2}\right)\)
Answer & Solution
Correct Answer
(A) \(\left(\frac{19}{2}, 6\right)\)
Step-by-step Solution
Detailed explanation
We know that, centroid divides median in the ratio 2:1. \(\begin{aligned}(7,5) &=\left(\frac{2 x+2}{2+1}, \frac{2 y+3}{2+1}\right) \…
