The given circle is x2+y2 = 169 The equation of its director circle is x2+y2 = 338 Since point (17, 7) satisfy the equation of director circle, the tangents, which are drawn from the point (17, 7) are mutually perpendicular and the locus of the perpendicular tangents is the director circle. Hence, both statements are true and Statement-2 explains Statement- 1.
