Question

The measure of one angle of a parallelogram is 80° . What are the measures of the remaining angles?

Answer 1

in a parallelogram opp angles are equal and opp sides are parallel. thus two angles on the same side are supplementary
therefore, in the parallelogram
the angle opp to the 80* will be 80*
and the other two angles will be
                   2x + 2(80*) = 360*
                   2x = 360* - 160*
                   x = 200*/2 = 100* 

Answer 2

Answer: 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

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

Hope you understand.
