Answer:
x = 5
Step-by-step explanation:
Since these are similar triangles, their side lengths form ratios. This is illustrated for the given two similar triangles below:
[tex]\frac{16}{10} = \frac{8}{x}[/tex]
Notice that we can divide 16 by 2 to get 8. Because of this, we can divide 10 by 2 to get the value of x. 10 ÷ 2 = 5, so 5 is the value of x.
Hopefully that was helpful! :)
