Explanation:

its adjacent angle is 180 - 60= 120⁰

its opposite angle is equals to 60⁰

emanshahzadi929

60 + 60 + x + x = 360 (because opposite angle of parallelogram is equal)

120 + 2x = 360

2x = 360 - 120

2x = 240

x = 240 / 2

x = 120

hence x=120

{here x is adjacent angle}

and the opposite angle is 60 degrees
