Question

Triangle ABC similar to Trianngle PQR if AB = 6, BC = 4, AC=8 and PR=6 then PQ + QR?

Answer 1

The answer would be....

Answer 2

Answer:

PQ+QR=7.5

Step-by-step explanation:

Given that  △ A B C ∼ △ P Q R △ABC∼△PQR

Then their corresponding sides are in the same ratio. ∴

$A B/ P Q = A C/ P R = B C /Q R$

∵   A B/ P Q = A C /P R

$6/PQ =8/6 \\ PQ=6*6/8 \\ PQ=4.5$

∵$\fr B C /Q R = A C /P R$

$4/QR=8/6$

$QR=3$

∴$PQ+QR=4.5+3\\\\\PQ+QR = 7.5$
