Answer :

Take the distance from xz and subtract xy in order to find yz. So if you subtract 21.4 and 13.8.....yz=7.6

Answer:

yz = 7.6

Step-by-step explanation:

Since, y lies in between x and z.

Thus, xy + yz = xz

⇒ yz = xz - xy

Also, we have, xy = 13.8

xz = 21.4

Hence, yz = 21.4 - 13.8

⇒ yz = 7.6
