Answer:
65
Step-by-step explanation:
A parallelogram is a quadrilateral (a four sided object) with parallel sides
Some of the characteristics of a parallelogram includes :
1. Opposite sides and angles are congruent .
2. Opposite angels are congruent
3. Consecutive angles are supplementary
4. The diagonals bisect each other
one side measures = 50 + x
the opposite side measures 50 + x
and the 2 other sides measure x
sum of angles in a parallelogram = 360
50 + x + 50 + x + x + x = 360
100 + 4x = 360
4x = 260
x = 65
