Answer & Solution

Correct Answer

(A) (3,3,1)

Step-by-step Solution

Detailed explanation

We have a parallelogram ABCD, whose vertices are A2,4,-1, B3,6,-1, C4,5,1 Now, assume the fourth vertex Dx,y,z So, we have diagonals AC and BD Now, we know that, diagonals of a parallelogram bisect each other, So, coordinate of E, as mid-point of AC is…
