touches ---> tangent ?
the radius of the smaller circle is perpendicular to the midpoint of the larger chord
the radius of the larger circle is the hypotenuse , and half of the chord is the longer side
use Pythagoras to find the radius of the smaller circle
hint: the triangle is a Pythagorean triple (all sides are integers)
