Respuesta :

let's see what to do...

Figure A is scaled image of Figure B.

So Figure A must be made in a proportion of Figure B.

We should find the ratio:

to find the ratio we have to use the same known sides.

[tex]ratio = \frac{5}{2} \\ [/tex]

Also we have :

[tex]ratio = \frac{12.5}{x} \\ [/tex]

So we have :

[tex] \frac{5}{2} = \frac{12.5}{x} \\ [/tex]

Multiply the sides by 2x :

[tex]5 \: x = 25 \\ x = 5[/tex]

And we're done.

Thanks for watching buddy good luck.
