Question

In the Given figure TriangleABR~TrianglePQR If PQ=30cm,AB=45cm,AP=72cm,QR =42cm Find PR,AR andBR

Answer 1

in the given figure, angle ABR -angle PQR. if PQ=30cm, AB = 45cm, AP =72cm, QR =42cm, find PR, AR and BR.

Answer 2

Thank you for asking this question. Here is your answer:

AP = 72 cm

AR = 45 cm

AP =  AR + PR

PR = AP - AR

= 72 - 45

= 27 cm

ΔABR ≈ ΔPQR

= AB/PQ = BR/QR = AR/PR

BR /42 = 45/27

BR = 45 x 42/27

= 70 cm
