Question

Please help, I am so confused

Answer 1

`\huge\boxed{25.2\ m}`

Explanation:

In order to find the length of the missing side here, we must note that these triangles are similar.

Therefore their lengths are proportionate to each other.

So,

`(27.6)/(11.5) = (x)/(10.5)`

We can solve for x by cross multiplying.

`10.5\cdot 27.6 = 289.8\\\\289.8 / 11.5 = 25.2`

Hope this helped!
