In the accompanying figure, semicircles with centers
and
have radii
and
, respectively. Furthermore, they are internally tangent to the circle of diameter
. Also the semicircles with centers
and
are externally tangent to each other. The circle with center
is internally tangent to the semicircle with diameter
and externally tangent to the others two semicircles. Determine the value of the radius of the circle with center
.
