The points on the line x = 2 from which the tangents drawn to the circle x2+y2=16 are at right angles is (are)

The point from which the tangents drawn are at right angle lies on the director circle.Equation of director circle x2+y2=2×16=32.Putting x = 2, we gety2 = 28or y=±27So, the points can be (2,27) or (2,−27)
