Answer:
The answer is x= 100 degrees
Explanation:
C. x = 100°
The sum of angles in a quadrilateral is 360°. The figures are given as congruent (even though they don't look like it), so corresponding angles have the same measure.
80° +75° +x +105° = 360°
x = 100° subtract 260°
It should be C) I did this too lol!!!
