Given

The parallelogram is given with angles


130\degree,130\degree,50\degree,5x\degreeStep-by-step explanation

To determine the x.

From the property of parallelogram, the sum of adjacent angles are 180 degree.


\begin{gathered} \angle D+\angle C=180\degree \\ \end{gathered}

Substitute the values.


\begin{gathered} 130\degree+5x\degree=180\degree \\ 5x\degree=180\degree-130\degree \\ 5x\degree=50\degree \\ x=10\degree \end{gathered}Answer

Hence the value of x is 10 degree.
