explain why the triangles are similar. then find the value of x

Answer:
D
Step-by-step explanation:
we are given 2 angles congruent(A) and another pair of angles are congruent the vertical ones(A) so is AA-postulate
x/8 = 7/12; multiply both sides by 8
x= 7*8/12 = 7*2*4/ 3*4 ; simplify
x= 14/ 3 = 4 and 2/3
