For this, you will be using proportions. And in this case, the proportion will be 
Firstly, cross-multiply: 
Next, subtract 5x on each side: 
Lastly, subtract 24 on each side, and your answer will be 6 = x
To find BC, just add 4 and 6 together, which is 10. And to find AC, add 10 and 2 together, which is 12.
In short, the answer is the first option.

Step-by-step explanation:
Consider the reflection in the y- axis
A point (x, y ) → (- x, y )
Consider the reflection of point A
A(- 5, 2 ) → A'(5, 2 )
Now A → E after the transformations
E = (4, 3 ), thus
A'(5, 2 ) → E(4, 3 )
(x, y ) → (x + (- 1), y + 1 ) = (x - 1, y + 1 )
