The locus of the mid-point of the chord of contact of tangents drawn from points lying on the straight line
4x 5y = 20 to the circle x2 + y2 = 9 is
(A) 20(x2 + y2) 36x + 45y = 0 (B) 20(x2 + y2) + 36x 45y = 0
(C) 36(x2 + y2) 20x + 45y = 0 (D) 36(x2 + y2) + 20x 45y = 0
What Is a proof for midpoint theorem ?
