`P(a,5a)` and `Q(4a,a)` are two points. Two circles are drawn through these points touching the axis of y.
Centre of these circles are at

Two circles are drawn through the points (1,5) and (4,1) to touch the axis of y. Find the angle at which they intersect.

Two points A and B are 16 cm apart. A circle with radius 17 cm is drawn to pass through these points. Find the distance of AB from the centre of the circle.
