hey mate here is your answer____
let side be x
then 4x and 5x are sides
so 4x+5x+4x+5x=360
18x=360
x=20
let side be x
then 4x and 5x are sides
so 4x+5x+4x+5x=360
18x=360
x=20

We know that opposite angles of parallelogram are equal
so Angle A= Angle C = 4x
Angle B = Angle D = 5x
A+B+C+D = 360
4x+5x+4x+5x = 360
18x = 360
x = 20
the angles are 80,100,80,100
Hope my answer would help u!!!
