In the given figure, \( \triangle ABC \) is circumscribing a circle. Find the length of \( BC \) a) \( 11 cm \) b) \( 12 cm \) c) \( 8 cm \) d) \( 10 cm \)

Answer»

The correct option is (d) 10 cm

Given, AR = 4 cm and, AR = AQ = 4 (Tangents from the same point are equal)

CQ = AC − AQ = 11 − 4 = 7 cm

CQ = CP = 7 cm (Tangents from the same point are equal)

BR = BP = 3 cm (Tangents from the same point are equal)

Now, BC = CP + BP

BC = 7 + 3 = 10 cm
