Answer
Steps of construction :
With O as center and radius = 3.5 cm draw a circle.
Take a point P such that OP = 6 cm.
Draw perpendicular bisector of OP, cutting OP at M.
With center M and radius OM, draw a circle which intersects the circle with center O at A and B.
Join AP and BP. Measure AP and BP.
Hence, AP and BP are required tangents.
On measuring,
AP = BP = 4.9 cm.
Hence, length of each tangent = 4.9 cm.
