Question

in the figure, CP and CQ are tangent to a circle with centre O. ARB is another tangent touching at the circle at R.if QC=11cm and BC=7cm​

Answer 1

ANSWER

CQ and CP are the tangents to a circle

So, CQ=CP (Tangents to a circle from a common point (C) are equal in length)

CP=CQ=11

Also, BC+BQ=11

⇒BC+7=11

⇒BQ=4

So, BR=BQ=4. (Tangents to a circle from a common point (B) are equal in length)

Thus, option D will be the answer.
