Answer:
In a parallelogram the opposite angles are equal. Therefore 5x - 8 = 2x + 82 5x - 2x = 82 + 8 3x = 90 x = 90 / 3 x = 30 5x - 8 = 5 ( 30 ) -8 ...

Answer:
*****In a parallelogram the opposite angles are equal.
⇒5x - 8 = 2x + 82
⇒5x - 2x = 82 + 8
⇒3x = 90
⇒x = 90 / 3
⇒x=30
***If u want the measures of each angle of a parallelogram it's here
5x - 8 = 5 ( 30 ) -8 = 150 - 8 = 142
2x + 82 = 2 ( 30 ) + 82
= 60 + 82 = 142
So All the angles of a parallelogram are 142, 38, 142, 38....
