Answer:
In Parallelogram
Sum of adjacent angles is 180
Opposite angles of Parallelogram are equal
Case I : If angles are adjacent angles
- 4x + 5x - 9 = 180
- 9x - 9 = 180
- 9x = 180 + 9
- 9x = 189
- x = 189/9
- x = 21
Case II : If angles are opposite to each other
- 4x = 5x - 9
- 5x - 4x = 9
- x = 9
Required Answers are Either x = 21 or x = 9
