Find each angle of a parallelogram if two consecutive angles are in ratio 1:5

let ABCD be a parallelogram.
let the angles be x and 5x.
therefore, x+5x=180{sum of consecutiove angels}
                    6x=180
                     x=30
 hence,angle A=30degree
          angle B=5x=5*30=150degree
         angle C=angle A=30degree
        angle D=angle B=150 degree
