Question

in figure pq parallel to bC find pb.pa=2.4 AQ=1.8 QC=5.4​

Answer 1

Answer:

PQ║BC

Therefore BPT Theorem proves that,

AP/PB = AQ/QC

2.4/1.8 = AQ/5.4

AQ= 7.2

Answer 2

Answer:

1.8 cm is the correct answer

Step-by-step explanation:

∵PQ∥BC

⇒∠APQ=∠ABC

and∠AQP=∠ACB(corespondinganglearesame)

∴△APQ∼△ABC(AAcriteria)

hence,

AB
