Answer:
56
Step-by-step explanation:
First, I drew picture of a line containing points W and Z.
Next, I added a midpoint between W and Z and labelled it Y.
Next, I added a midpoint between W and Y and labelled it X.
It is given that XY = 14, so that means WX is also 14 (because X is the midpoint, these two distances have to the be the same)
Now I know WY is 28, which means YZ is also 28.
So WZ has to be 56.
