Question

the measure of one of the angles of a parallelogram is 130 degree.
What are the other angles?

Answer 1

suppose angle A=130 degree ; in parallelogram opposite angles are equal so angle A=angle C=130 degree therefore angle B also = angle D =x according to question angleA+ angle B + angle C + angle D= 360 degree 260 degree +2x =360 degree 2x=360 degree _ 260 degree 2x =100degree x= 100 degree ÷2=50 degree

Answer 2

Answer.
Let ABCD be a parallalogram
Side AB = CD
Side AD = BC
Angles A and B form a linear pair
and angles C and D form a linear pair
Measure of angle A = C
and Measure of angle B = D
Angle A = C = 130
Angle B = D = 70
