Question

In the given figure, PQ, PR and BC are the tangents to the circle. BC touches the circle at X. if PQ=7 cm, then the perimeter of triangle PBC is,

A) 9 cm
B) 12 cm
C) 14 cm
D) 21cm​

Answer 1

answer: 14cm

• PQ=7cm
• PB+BQ=7 cm
• PQ=PR (tangents are equal)
• PC+CR=7 cm
• BX=BQ and CX=CR (tangents)
• Perimeter = PB+BX+CX+PR = 7 +7=14
