Question

in figure seg PQ||BC if bp =6 ab=14 AQ=4 find QC

Answer 1

By BPT or Thales theorm:

AP/PB=AQ/QC

8/6=4/QC

(by cross multiplication)

We get;

8*QC=4*6

QC=24/8

QC=3cm

Hence Proved

Answer 2

Sold:-
By basic proportionality theorem ,
In triangle ABC,

AP/PB=AQ/QC

8/6=4/QC
QC=6*4/8
QC=3

Ans: QC =3 units
