Mamont248 [21]

Answer:

D. 2

Step-by-step explanation:

DEFG is a trapezoid and AB is its Midsegment.

Therefore,

AB =\frac{1}{2}(DG + EF)  \\  \\ 12 =  \frac{1}{2} (5x - 4 + 8x + 2) \\  \\ 12  \times 2= (13x - 2) \\  \\ 24 = 13x - 2 \\  \\ 24 + 2 = 13x \\  \\ 26 = 13x \\  \\ x =  \frac{26}{13}  \\  \\ x = 2
