diameter: UW
2) OD= 4.8
3)x =7 SV=6
Explanation:
tangent line : A tangent to a circle is a straight line which touches the circle at only one point
secant:A secant is a line that intersects a circle in exactly two points
diameter: diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle
