Answer:
The value of XY is 20.
Explanation:
Given:
XZ = 16
YZ = 12
Since the triangle is not shown:
Assuming it is a right angled triangle with right angle at ∠Z.
We have drawn the triangle for your reference.
Now by Using Pythagoras theorem we get;

Substituting the values we get;

Now taking square root on both side we get;

Hence The value of XY is 20.
