    Wegnerkolmp2741o is wrong.

    Step-by-step explanation:

    of one side of the paralleogram is 60 then so is another side

    a

    b=60

    c=60

    d=

    2a+120=360

    -120 - 120

    240

    divide 240 by 2 and angles a and are 120

    one way to check this is to multiply 120 by 3 and you get 360

    The remaining 3 angles are 300 degrees

    Step-by-step explanation:

    The sum of the interior angles of a parallelogram is 360 degrees

    We know one angle is 60

    360 - 60 = 300

    The remaining 3 angles are 300 degrees
