Given, In the diagram, CD is tangent to circles A nad B amd the circles are tangent to each other.

CD=15, AB=17 and CB=6

Now,

From the diagram, we can say that CB and BE is the radius of the circle B and AD and AE is the radius of the circle A.

So,$\therefore AB=BE+AE[\because CB=BE]$

$\Rightarrow 17=CB+AE$

$\Rightarrow 17=6+AE$

$\Rightarrow AE=17-6$

$\Rightarrow AE=11$

$\therefore AD=AE=11$

$\therefore AD=11$

CD=15, AB=17 and CB=6

Now,

From the diagram, we can say that CB and BE is the radius of the circle B and AD and AE is the radius of the circle A.

So,
