Question

in given figure,∆ABR~∆PQR. if PQ=30cm,AR=45cm,AP=72cm,QR=42cm, find PR,AB and BR​

Answer 1

Answer:

Step-by-step explanation:

Given:

PQ=30cm

AR=45cm

AP=72cm

QR=42cm

To prove:

PR,ABand BR

Prove:

AP-AR=PR

72-45=PR

27=PR

Answer 2

RP=AP-AR

=72-45

=27cm

ABR~PQR

AB/PQ=BR/QR=AR/PR

BR/42=45/27

BR=45×42÷27

BR=70cm

AB/PQ=BR/QR
AB=70×30÷42
AB=50
