Answer:

D. [tex]x=10[/tex]

Step-by-step explanation:

You can use the Pythagorean Theorem, [tex]a^2+b^2=c^2[/tex], where a and b are the legs and c is the hypotenuse.

[tex]12^2+b^2=13^2\\144+b^2=169[/tex]

Subtract 144 from both sides

[tex]b^2=25[/tex]

Square root both sides

[tex]b=5[/tex]

[tex]2b=x\\b=5\\x=10[/tex]
