Answer:
D
Step-by-step explanation:
Since this triangle is already separated in half, you can use the pythagorean theorem to find the base of each of them and then just add them back together. [tex]\sqrt{\sqrt{13}^2-2^2}=\sqrt{13-4}=3[/tex]. Multiplying this by 2, you get a total base value of x=6, or answer choice D. Hope this helps!
