Q. 12 D5.0( 3 Votes )

# In the adjoining figure, two tangents drawn from external point C to a circle with centre O touches the circle at the points P and Q respectively. A tangent drawn at another point R of a circle intersects CP and CA at the points A and B respectively. If CP = 11 cm. and BC = 7cm, let us determine the length of BR.

CP = CQ = 11 cm (Tangents drawn from an external point to the same circle are always equal)

BC = 7 cm (Given)

BQ = (CQ-BC) = 4 cm

BQ = BR (Tangents drawn from an external point to the same circle are always equal)

BR = 4 cm
