Question

in the given figure triangle ABR is similar to triangle pqr if PQ is equal to 30 cm a b is equal to 45 cm is equal to 72 CM QR is equal to 42 cm find PR,AR and BR

Answer 1

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

IF there is any confusion please leave a comment below.

Answer 2

Answer:

Step-by-step explanation:

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
