Remember that the sum of the values of the interior angles in a four-sided shape is 360 degrees, given to us by the formula
180(n - 2), where
n is the number of sides the shape has.


By this we can say:


x + 92 + 47 + 82 = 360


x + 221 = 360


x = 139


The value of our angle,
x, is 139 degrees.
