Answer:
D
Step-by-step explanation:
So to solve for AC you'll want to find the hypotenuse for ACD. In order to do that, we need the length of AD. We can find it by using the pythagoram theorum. So 7²=A² + 5²=> 49=A²+25 so A =[tex]\sqrt{24}[/tex]
Now that we have AD we can find x which is A²=24+9=A=[tex]\sqrt{33}[/tex][tex]\sqrt{33} x^{2}[/tex]
