What is x? If necessary, round to the nearest tenth (one decimal place):

Answer:
x = 10
Step-by-step explanation:
Both right triangles are similar.
-> Corresponding sides of similar triangles are in proportion.
[tex] \implies \: \frac{x + 6}{16} = \frac{x}{10} \\ \\ \implies \: 10(x + 6) = 16x \\ \\ \implies \: 10x + 60= 16x \\ \\ \implies \: 10x - 16x = - 60 \\ \\ \implies \: - 6x = - 60 \\ \\ \implies \: x = \frac{ - 60}{ - 6} \\ \\ \implies \: x = 10[/tex]
