In a parallelgram opposite angles are equal
 
i.e..(3x-2)=(63-2x)
3x-2=63-2x
3x+2x=63+2
5x=65
x=65/5
x=13

substituting x =13 we get
3×13-2=63-2×13
37 = 37

so the angles are 37° , 180°-37°,37° and 180°-37°
i.e. 37°,143°,37°and 143°

(3x - 2) = (63 - 2x) (opp angles are equal)
3x + 2x = 63 + 2
5x = 65
x = 65/5 = 13

3 * 13 - 2 = 37
63 - 2 * 13 = 37
Sum of 2 angles = 74
Total sum of angles in a parallelogram = 360
360-74 = 286 
286/2 = 143
Therefore angles are 37, 143 , 37 & 143.
