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 |
