Question

There are two concentric circles with centre o. Prt and pqs are tangents to the inner circle from a ppint p lying on the outer circle. If pr=5cm, find the length of ps

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Given:

PQS and PRT are tangents to inner circle.

PR = 5 cm

To find:

PS=?

As we know,

PR = PQ = 5cm ( tangents from common point)

And also,

PQ = QS = 5cm (OQ is the radius, so it bisects PS)

Therefore,

PS = PQ + QS =  5+5= 10 cm

PS=10 cm
