Answer:
x = 6
Step-by-step explanation:
find the x value for one triangle then times it by 2
Pythagorean Theorem: [tex]a^{2}+b^{2}=c^{2}[/tex]
[tex]c=\sqrt{13}[/tex]
[tex]a=2[/tex]
Square c and subtract a from it.
[tex]13-4 = 9[/tex]
square root 9 to get have of the x value, then multiply it by 2
[tex]2\sqrt{9}=6[/tex]
[tex]x=6[/tex]
