Answer:

10m

Step-by-step explanation:

We can set up an equation to solve this.

\frac{20}{25} =\frac{8}{x}

This equation can be created since we are given two similar sides of both triangles.

Now, cross multiply and simplify to solve for x.

20x=200\\x=10

The answer is sensible, and if you put 10 into the same equation from earlier, you will see that it is accurate.

Therefore, the value of x is 10m.
