Answer: 14
Step-by-step explanation:
Since they are similar, that means their side lengths are proportional.
Therefore, [tex]\frac{WX}{AB} = \frac{WZ}{AD}[/tex].
We can plug in the values we know:
Let x be the missing measurement.
[tex]\frac{16}{24} =\frac{x}{21}[/tex]
We can simplify 16/24 to 2/3.
2/3 = x/21.
We can cross multiply:
42 = 3x
Therefore, x = 14
