Question

y is the midpoint of $overline{wz}$. x is the midpoint of $overline{wy}$. wy = 5. what is the length of $overline{xz}$?

Explanation:

Step1: Find the length of WX

Since X is the mid - point of WY and WY = 5, then WX=\frac{1}{2}WY.
WX=\frac{1}{2}\times5 = 2.5

Step2: Find the length of YZ

Since Y is the mid - point of WZ and WY = 5, then YZ = WY = 5.

Step3: Calculate the length of XZ

XZ=XY + YZ. And XY=WX = 2.5, YZ = 5.
So XZ=2.5+5=7.5

Answer:

7.5
