Solution 
Given : Radius = 4cm

Steps of construction
1.  Draw a circle at radius r = 4 cm at point O. 
2.   Take a point P at a distance of 6cm from point O and join PO
3.  Draw a perpendicular bisector of line PO M is the mid-point of  PO.
4.   Taking M as the centre draw another circle of radius equal to MO and it intersects the given circle at points Q and R  

5.   Now, join PQ and PR.
Then PQ and PR one the required two tangents.
