Answer: 40
Step-by-step explanation:
Opposite sides of a rhombus are parallel, so by the alternate interior angles theorem, angle ABE measures 50 degrees.
Also, the diagonals of a rhombus are perpendicular, so angle AEB is 90 degrees.
Thus, as angles in a triangle (in this case AEB) add to 180 degrees, x=40.
