Answer:

B. 7

Step-by-step explanation:

The figure is a rhombus, so the line AC is a bisector line of the angleBAD, so that means that the angleBAE and angleDAE have the same measure, and the angleBAD is the sum of angleBAE + angleDAE, so:

(9x + 2) + (9x + 2) = 130°

18x + 4 = 130°

18x = 130 - 4

18x = 126

x = 126/18

x = 7
