Answer:
3x+8+10-x = 180
2x+18 = 180
x = 180-18/2 = 162/2 = 81
then the angles are 3×81+8 = 235!!!!
I think question have some defect...... amend it...

Adjacent angle of parallogram =180
=>3x+8+10-x=180
=> 2x+18=180
=>2x=180-18
=>2x=162
x=162/2
x=81
The value of x=81
So,we put. in ..it.
3x+8
=>3×81+8
=>243+8
= 251
3x+8=251
10-x
10-81
=>(-71)
So for prove. :-
251+(-71)=180
251-71=180
180=180
