Question

If an angle of a parallelogram is two third of its adjacent angle find the angles ofparallelogram​

Answer 1

Measures of Adjacent angles of parallelogram are :- 180 degree

2/3 y + y = 180 degree

2/3 y + 3/ 3 y = 180 degree

5/3 y = 180 degree

Y= 180 x 3 / 5

Y= 108 degree

2/3 degree = 2/3 x 180 = 72 degree

Opposite angles are same in parallelogram so angles are:-

72,108,72,108 degrees
