    Yes You can find the lengths of CD, AD and DB from the given information and therefore the areas of the 2 triangles. There is a relation between the radii of the incircles of a triangle and its area. Knowing the radii of the 2 circles you can find PQ.

    I cant recall that relation but its no doubt on the web somewhere

    Yea r = A/s where A is the area of the triangle ans = semi perimeter of the triangle.

    I've used x , y and z for the line segments AD, DB and CD so we get x + y = 25 15^2 + x^2 = z^2 20^2 + y^2 = z ^2 the last 2 are by the Pythagoras theorem
