Math Problem Statement
Line (XY) is a secant to the larger circle and is tangent to the smaller circle at point (Q). The radius of the smaller circle is (7) and the radius of the larger circle is (9). What is the length of chord (XY)?
(8\sqrt{2}\approx11.31) (16) (\sqrt{130}\approx11.4) (4\sqrt{2}\approx5.66)
