Solution

The correct option is A

Points where $x + 7 = 0$ meets the circle $x^{2} + y^{2} = 50$ are $(- 7, 1)$ and $(- 7, - 1)$ . Hence equations of tangents at these points are $- 7 x \pm y = 50$ or $7 x \pm y + 50 = 0$

The equations of the tangents to the circle x2+y2=50 at the points where the line x+7=0 meets it, are

The correct option is A Points where x+7=0 meets the circle x2+y2=50 are (−7,1) and (−7,−1). Hence equations of tangents at these points are −7x±y=50 or 7x±y+50=0
