Question

I really need help with number 7 find the value of x that makes abcd a parallelogram.

Answer 1

Given

The parallelogram is given with angles

`130\degree,130\degree,50\degree,5x\degree`Step-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.
