#### Solution

**Steps of construction:**

- With centre O, draw a circle of radius 3 cm.
- Take point P and Q such that OP = 7 cm and OQ = 7 cm.
- Draw the perpendicular bisector of seg OP. It intersects OP in point M.
- Also, draw the perpendicular bisector of seg OQ. It intersects OQ in point N.
- With M as centre and radius equal to PM, draw an arc intersecting the circle in points R and with N as centre and radius equal to NQ, draw an arc intersecting the circle in points S.
- Draw rays PR and QS.

Rays PR and QS are the required tangents to the circle.
