Question

Need help on what it is!!!

Answer 1

It's not C. Use the Geometric Mean for right triangles to solve. In our formula, our values will fit in like this:
`(9)/(x)=(x)/(9+7)`. Simplifying we have
`(9)/(x)=(x)/(16)`. Cross-multiply to get
`x^2=144`. That means that x = 12. First choice above.

Answer 2

km pretty sure it’s C (the third one )
