The correct answer is:
$ \displaystyle 3\sqrt{3}$ cm
$ \displaystyle 3\sqrt{3}$ cm
Explanation:
Let be an external point and a pair of tangents is drawn from point and angle between these two tangents is 60°.
Join and .
Also, is a bisector line of .
Tangent at any point of a circle is perpendicular to the radius through the point of contact.
In right angled .
Hence, the length of each tangent is $ \displaystyle 3\sqrt{3}cm$.
