Question

the measure of the two vertically opposite angle aren140 and (x+40) respectively find the value of x

Answer 1

Answer:

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
