Question

given ∆JKL : ∆XYZ, find x.

A. 10

B. 12

C. 16

D. 20

Answer 1

ΔJKL : ΔXYZ

for two similar triangles we have this property:

$\frac{JK}{XY} =\frac{KL}{YZ}$

plugging the given values to find x

$\frac{6}{9} =\frac{8}{x}$

cross multiplying ,

6*x=8*9

6x =72

x=12

Answer 2

the answer would be 12
