Expert Answer:

Steps of construction:

1. Draw two concentric circle with centre O and radii 4 cm and 6 cm. Take a point P on the outer circle and then join OP.

2. Draw the perpendicular bisector of OP. Let the bisector intersects OP at M.

3. With M as the centre and OM as the radius, draw a circle. Let it intersect the inner circle at A and B.

4. Join PA and PB.

Therefore, are the required tangents.
