Hope it helps!! Mark this answer as brainliest if u found it useful and follow me for quick and accurate answers...

Step-by-step explanation:

step 1:--Draw a circle of radius 3•5cm taking as a centre.

step 2:--Extend the diameter, on extended diameter take two points A and B in two directions,OA = OB=8cm.

step3:--Draw perpendicular bisector of OA, the bisector cuts OA at P.

step 4:--Draw perpendicular bisector of OB, the bisector cuts OB at Q.

step 5:--Taking P as center and radius equal to length OP or PA, draw a circle.

step 6:--Two circles intersect each other at K and L.

step 7:--join AK and AL, AK and AL are the required tangents from point A.

step 8:--Now taking Q as center and radius equal to length OQ or QB, draw a circle,

step 9:--The circle with centre O and centre Q intersect each other at M and N.

step 10:-- Join BM and BN, BM and BN are the required tangents from point B.
