Application +4 | -1

Angle between the straight line

\frac{x-1}{2}=\frac{y+3}{-1}=\frac{z-5}{2}

and the plane

4 x-2 y+4 z=9

View answer and explanation

Correct option: B

90^{\circ}

Option B (2) is correct. Since the point (-1, 2) lies outside the circle, there are two tangents that can be drawn from the point to the circle.
