Answer 2

Answer:

360* ,  160* , 100*

Step-by-step explanation:

In a parallelogram opposite angles are equal and opposite sides are parallel. thus two angles on the same side are supplementary

Angle opposite to 80* will be 80*

and the other two angles will be

2x + 2(80*) = 360*

2x = 360* - 160*

x = 200*/2 = 100*
