No, 12 is the wrong answer. 5 is correct
This is because since a and c are congruent that means y=52. And we already know that every triangle adds up to 180 degrees so, you add A and C and get 104 (52+52).
And 180-104=76 so, 14x+6 must =76.
14(5)=70+6=76. 76+104=180, therefore, x=5.
It's ASA
<C = <D
CB = DE
<B = <E
hope it helps
