Question 8 :
A line touches a circle of radius 4 cm. Another line is drawn which is tangent to the circle. If the two lines are parallel then distance between them is
Question 9 :
OA, OB are the radii of a circle with 0 as the center, the $\angle AOB = 120^o$. Tangents at A and B are drawn to meet in the point C. If OC intersects the circle in the point D, then D divides OC in the ratio of
