The value of x would be 35.
That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
In order to calculate the value of x in the parallelogram, we have to find the following;
Let ∠m = 2x - 10
∠n = 2x + 50
So, ∠m + ∠n = 180
2x-10 + 2x+50 = 180
4x + 40 = 180
4x = 180 - 40
4x = 140
x = 35
Hence, the value of x is 35.
