Answer 1

`\boxed{\boxed{\sf{a=5}}}`

Solution Steps:

____________________________

1.) Fill in the formula:

• F =
  `B^2-C^2=A^2`

• F =
  `12^2-13^2=A^2`

• F =
  `144-169=A^2`

2.) Subtract:

• 
  `169-144=25`

3.) Find the square root of 25:

• 
  `√(25) =5`

So your answer would be C,
`\bold{a=5}`.
