In a parallelogram, opposite angles are equal, so, lets draw a picture of our parallelogram:
since interior angles of a parallelogram add up to 360 degrees, we can write
[tex]70+70+x+x=360[/tex]
By combining similar terms, we get
[tex]140+2x=360[/tex]
so, by moving 140 to the right hand side, we have
[tex]\begin{gathered} 2x=360-140 \\ 2x=220 \end{gathered}[/tex]
and x is given by
[tex]\begin{gathered} x=\frac{220}{2} \\ x=110 \end{gathered}[/tex]
therefore, the answer is 110 degrees
