Question

If one angle of a parallelogram is 80°. the sum of other two opposite angles is ​

Answer 1

Answer:

total sum= 360°

If one angle is 80°, then its corresponding angle will also be 80°.

A.T.Q

x+×+80°+80° = 360°

2x + 160° = 360°

2x = 360°-160°

2x= 200°

× =100°

hence, the angles are 80°, 80°, 100°,100°

Answer 2

Step-by-step explanation:

Step-by-step explanation:in a parallelogram opposite angle are equal and opposite sides are parallel.thus two angle on the same side are supplementary. therefore, in the parallelogram the opposite 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 angle of parallelogram are 100,80,100,80
