Answer:
![XY=36\ units](https://tex.z-dn.net/?f=XY%3D36%5C%20units)
Step-by-step explanation:
<u><em>The correct question is</em></u>
A, B, and C are midpoints of ∆XYZ. What is the length of XY
we know that
The<u><em> Midpoint Theorem</em></u> states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side
step 1
Find the length of YZ
![AB=\frac{1}{2}YZ](https://tex.z-dn.net/?f=AB%3D%5Cfrac%7B1%7D%7B2%7DYZ)
we have
![AB=24\ units](https://tex.z-dn.net/?f=AB%3D24%5C%20units)
substitute
![24=\frac{1}{2}YZ](https://tex.z-dn.net/?f=24%3D%5Cfrac%7B1%7D%7B2%7DYZ)
solve for YZ
![YZ=48\ units](https://tex.z-dn.net/?f=YZ%3D48%5C%20units)
step 2
Find the length of XY
Applying Pythagoras Theorem in the right triangle XYZ
![XZ^2=XY^2+YZ^2](https://tex.z-dn.net/?f=XZ%5E2%3DXY%5E2%2BYZ%5E2)
substitute the given values
![60^2=XY^2+48^2](https://tex.z-dn.net/?f=60%5E2%3DXY%5E2%2B48%5E2)
solve for XY
![3,600=XY^2+2,304](https://tex.z-dn.net/?f=3%2C600%3DXY%5E2%2B2%2C304)
![XY^2=3,600-2,304](https://tex.z-dn.net/?f=XY%5E2%3D3%2C600-2%2C304)
![XY^2=1,296](https://tex.z-dn.net/?f=XY%5E2%3D1%2C296)
![XY=36\ units](https://tex.z-dn.net/?f=XY%3D36%5C%20units)
Applying the Midpoint Theorem
