Common Tangents of Two Circles - Direct and Transverse Common Tangent

There are two identical circles of radius 10 cm each. If the length of the direct common tangent is 26 cm, then what is the length (in cm) of the transverse common tangent?

Two circles of radius 4 units and 3 units are at some distance such that the length of the transverse common tangent and the length of their direct common tangent are in the ratio 1 : 2. What is the distance between the centres of those circles.
