Geometry

Question Analysis:
This problem tests the parallelogram condition involving opposite sides being congruent.
The main focus is solving equations based on opposite sides being equal in a parallelogram.

Key Concept Explanation:
In a parallelogram:
WX ≅ YZ → 3x – 5 = x + 7
XY ≅ WZ → 3x + 1 = 2x + 7
Solve both equations to find x.

Step-by-Step Solution:
Set WX = YZ:
→ 3x – 5 = x + 7
→ 2x = 12
→ x = 6 
Set XY = WZ:
→ 3x + 1 = 2x + 7
→ x = 6
Both conditions satisfied at x = 6

Common Mistakes:
Solving only one pair of equal side...
