Answer:

→Option(a) : 120°,60°,120°,60°.

_____________________________________

Explanation:

Let the two adjacent angles be x° and 2x° .

In a parallelogram, sum of the adjacent angles are 180°.

∴ x + 2x = 180°    

→ 3x = 180°    

→ x = 60°    

Thus , the two adjacent angles are 120° and 60°. Hence, the angles of the parallelogram are 120°, 60°,  120° and  60°.
