Answer:
x = 13
Step-by-step explanation:
First start with the blank equation
[tex]a^{2} + b^{2} = c^{2}[/tex]
Plug in the legs and hypotenuse. Remember c squared is always the hypotenuse.
[tex]5^{2} + 12^{2} = c^{2}[/tex]
Then solve
25 + 144 = [tex]c^{2}[/tex]
169 =[tex]c^{2}[/tex]
[tex]\sqrt{169} = \sqrt{c^{2} }[/tex]
c = 13
