Point C divdies the semicircular arc AB of radius 10 in such a way that the product of chords AC and BC is 100.  Find the central angles of the chords.

Not sure if this is what is meant by "central angle"!.  If "central angle" means, say, AOC, where O is the centre of AB, then this would be 180° - 2CAB
