Answer 2

The answer is 12 units.

Explanation:

Looking at the figure we see that

`(1).9^2+x^2=SR^2`

`(2).16^2+x^2=RQ^2` and

`(3).SR^2+RQ^2=(9+16)^2`

Now from equations (1) and (2) we have values for
`SR^2` and
`RQ^2,` so we put those into the equation (3) and get:

`9^2+x^2+16^2+x^2=(9+16)^2`

`\rightarrow 337+2x^2=625`

`\boxed{\therefore x= 12.}`

Therefore the answer is 12 units.
