Here is the solution my friend
Q.6 Given :- PA = 12cm
QC=QD=3cm
To find:- PC + PD
Solution :- PA & PB are tangents drawn from an external point therefore PA =PB
=> PB = 12cm
Now
QC = AC =3 { tangents drawn from an external point are equal, here C is the external point}
Similarly QD = DB = 3 cm .
Therefore PC = PA - AC
= 12-3
= 9
PD=PB - DB
=12-3
= 9
PC + PD = 9+9 = 18
