Answer:
38
Step-by-step explanation:
By CPCTC, angles C and D are congruent.
130 = 4x - 14
144 = 4x
x = 38
The quadrilateral is a parallelogram so opposite angles are equal
[tex]\\ \rm\Rrightarrow 4x-14=130[/tex]
[tex]\\ \rm\Rrightarrow 4x=130+14[/tex]
[tex]\\ \rm\Rrightarrow 4x=144[/tex]
[tex]\\ \rm\Rrightarrow x=36[/tex]
