Question

11.
In the given fig, CP and CQ are tangents to a circle with certre 0 and line segment AB touches the
circle at R with CP = 11cm, AR = 3cm, BC = 7cm, then BR is equal to

Answer 1

Step-by-step explanation:

Given CP = 11 cm CP = CQ = 11 cm { tangents to the circle from external point are equal in lengths } Given AR = 3 cm AR = AP = 3 cm { tangents to the circle from external point A are equal in lengths } Also given BC = 7 cm BR = BQ { tangents to the circle from external point B are equal in lengths } BQ = CQ - BC = 11 - 7 = 4 cm ∴ BR = BQ = 4 cm.
