Find the missing side

Romashka-Z-Leto [24]

Hi there!
The question here is basically asking us to use ratios to find the length of the missing side. To do this, we must first construct a ratio. The best one would be -
$\frac{84}{12} = \frac{56}{x}$
Now, just cross multiply and solve for x.
$\frac{84}{12} = \frac{56}{x}$
$84x = 672$
$x = 8$
Therefore, the length of the missing side would be 8. Hope this helped!
