Question

circle with center O touches the side of the triangle P Q R AB =AC. AQ=4 centimeter and CQ=6 cm. what is the length of cp. find the peimeter and are of triangle. what is the radium of the circle​

Answer 1

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.
