Answer:

60 degrees

Step-by-step explanation:

First we need to know how many degrees are in a parallelogram. We can use the formula 180(n-2) (n is the number of sides)

This works out to 180(4-2)=360 degrees.

Now we can set up the following equation as:

2(120)+2x=360 Subtract 240 from both sides to get:

2x=120 Divide by 2 to get:

x=60 degrees

Therefore we know 2 angles are each 120 degrees and the other 2 are 60 degrees.
