Let the common ratio be =x

Then,
2x+7x=180 (adjacent angle of parallelogram is supplementary)

9x=180
X=180/9=20
One angle is 2(20)=40
Other angle=7(20)=140

2x+7x=180°(sum of adjacent angles of ||gm)
9x=180°
x=180/9
x=20°
Angles of||gm =2×20=40°. ,7×20=140°
opposite angles of ||gm are equal. so other angles are,140°and 40°
