Question

If ∆PQR~∆XYZ , PR/XZ=2/3 , PQ= 12.Find XY​

Answer 1

Answer:

18

Step-by-step explanation:

given: PR / XZ = 2 / 3

We know that in if triangles are similar, their corresponding sides are similar too

therefore:-

PR / XZ = PQ / XY

2 / 3 = 12 / XY

by cross multiplication:-

2(XY) = 36

XY = 18

Answer 2

∆PQR~∆XYZ                        ( given)

PR / XZ = 2 / 3                      ( given)

When two Δ are similar, their corresponding sides will be similar too

∴PR / XZ = PQ / XY

⇒2 / 3 = 12 / XY

In next step we will apply cross multiplication process.

⇒2(XY) = 36

⇒XY =36 ÷2= 18

Hence XY will be 18.

Ans:- XY = 18
