Answer:
20
Option D is the correct option.
Step-by-step explanation:
As they are similar, correspondence sides are in common ratios:
[tex] \frac{x}{10} = \frac{10}{5} [/tex]
Apply cross product property
[tex]5x = 10 \times 10[/tex]
Multiply the numbers
[tex]5x = 100[/tex]
Divide both sides of the equation by 5
[tex] \frac{5x}{5} = \frac{100}{5} [/tex]
Calculate
[tex]x = 20[/tex]
Hope this helps...
Best regards!!
