A triangle ABC circumscribes a circle of radius 4 cm. AB, BC and CA are the tangents of the given circle. D is the point of contact such that AD = 6 cm and DB = 8 cm. Find the lengths of other sides viz. BC and CA. This problem has come under Tangent to the Circle. I do not know how to go about?

Kindly enlighten me.

Advance Thanks.
