Answer:

The right answer is x=8 and YZ=16

Step-by-step explanation:

To resolve this problem, we need to know that

XY+YZ=XZ (this is because of the length XY + the length of YZ= the length of XZ.

replacing the data given before we have:

12+2X=28

12-12+2X=28-12

now we subtract 12 on both sides of the operation:

2X=16

and finally, divide both sides by 2

[tex]\frac{2x}{2}[/tex]=[tex]\frac{16}{2}[/tex]

X=8

now knowing x, we can replace the value in "YZ=2X"

YZ=2X

Replacing =

YZ=2(8)

YZ=16

SO, X= 8 and YZ=16
