Answer:
SR=10cm ; PS=8cm
Step-by-step explanation:
We know that two tangents intersecting at any outerside of circle are equal
So, at Point P
PA=PB
PB=3cm .........(i)
At Point S
SC=SB
SC=5cm ..........(ii)
At Point R
RC=RD ..........(iii)
At Point Q
QD=AQ
QD=4cm .........(iv)
SP=SB+PB
PS=5cm+3cm [from (i)]
PS=8cm
QR=QD+RD
9cm=4cm+RD [from (iv)]
RD=5cm ..........(v)
SR=SC+RC
SR=SC+RD [from (iii)]
SR=5cm+5cm [from (ii) and (v)]
SR=10cm
