Let the biggest angle be x.therefore smallest angle=2x/3
we know sum of adjacent angles in parallelogram is 180.
now the smallest angle is 2x/3
therefore smallest angle=72
1 5 1
72 degrees
let 1 angle be x
then other adjacent angle will be 2/3x
we know that sum of adjacent angles is 180
x + 2/3x = 180
x = 108
smallest angle will be 72 degrees
