Hi,

parallelograms are composed of two pairs of equal angles (the opposite angles are equal), with each adjacent pair of angles summing to 180 degrees.

So, if we know that:

x + y = 180

and

x - y = 30

We can solve for both angles.

Subtracting the second equation from the first (if we wanted to solve for the bigger angle, we would have added instead of subtracted), we get:

2y = 150

y = 75

choose (A)!
