Question

PQ PR and BC are the tangents to a circle BC touches the circle at X if PQ is 7cm amd then the perimeter of triangle PBC is. hint perimeter of the triangle is 2PQ​

Answer 1

Answer:

perimeter of the triangle = 14 cm

Step-by-step explanation:

PQ & PR are tangents

=> PQ = PR = 7 cm

BC is also tangent

=> BQ  & CR are also tangents as B & C lies on PQ & PR

=> BQ = BX    & CQ = CR

Perimeter of Traingle PBC

PB + PC  + BC

PB = PQ - BQ

PC = PR - CR

BC = BX + CX

=> Perimeter = PQ - BQ + PR - CR  +  BX + CX

BQ = BX    & CQ = CR   & PQ = PR = 7

= 7 - BX + 7 - CR + BX + CR

= 14

perimeter of the triangle = 14 cm
