SOLUTION:
The angle sum of a quadrilateral is equivalent to 360°.
Angle sum of a quadrilateral = 360°
The angle directly opposite ( x ) is also equivalent to ( x ).
Therefore:
2x + 90 + 26 = 360
2x = 360 - 90 - 26
2x = 244
x = 244 / 2
x = 122
FINAL ANSWER:
Therefore, the answer is:
x = 122°
Hope this helps! :)
