25 cm, PB=5 cm and AQ=1.5 cm. Find QC​

Answer 1

Answer:

YZ=20cm

Step-by-step explanation:

$sol {}^{n}$

A PQR and AXYZ are similar , Their corresponding

sides are proportional.i.e

PQ/XY=QR/YZ=PR/XZ

=> PQ/XY=QR/YZ

=>PQ/2PQ=QR/YZ ( given 2PQ= XY)

=>1/2= QR/YZ

=>YZ=2QR

=>YZ= 2×10cm (given QR= 10 cm)

So, YZ = 20 cm

. .

Answer 2

Answer:

According to Question,

2PQ=XY

QR=10cm

Since, APQR and AXYZ are similar,

if 2PQ=XY

likewise 2RQ=YZ

or, 2*10cm=YZ

or, 20cm=YZ

therefore,

YZ=20cm
