Question :

If angle of parallelogram is four-fifths of its adjacent angle, then find the angles of parallelogram.Submitted on 23/12/2023 | Answered by Vandana Rana

Answer :

Let one angle be x
Other angle =4x/5
Now,

 X+4x/5 =180 (sum of co- interior angle) 
9x=180×5
 X=900/9 
X=100
 4x/5 =80

Each angle of parallelogram are 100,80,100,80
