Answer»

Explanation:

In a PARALLELOGRAM OPPOSITE angles are equal and opposite sides are parallel. THUS two angles on the same side are supplementary

therefore, in the parallelogram

the angle opposite to the 80* will be 80*

and the other two angles will be

2X + 2(80*) = 360*

2x = 360* - 160*

x = 200*/2 = 100*

The angles of parallelogram are 100,80,100,80
