In the given figu

Answer :

As we know, Tangents drawn from an external point are equal.


CR = CQ [tangents from point C]


CQ = 3 cm [as CR = 3 cm]


Also,


BC = BQ + CQ


7 = BQ + 3 [BC = 7 cm]


BQ = 4 cm


Now,


BP = BQ [tangents from point B]


BP = 4 cm …[1]


AP = AS [tangents from point A]


AP = 5 cm [As AC = 5 cm] ….[2]


AB = AP + BP = 5 + 4 = 9 cm [From 1 and 2]


AB = x = 9 cm
