Could someone explain this to me - I’m rather confused.

According to angle property of parallelogram, opposite angles are equal.

Therefore, 3x=4y

This is possible if x=4 and y=3.

Therefore x is greater than 3.

Note →

In generalized form, this is possible when x is in multiples of 4 and y is in (same) multiples of 3

i.e x=4m and y=3m (m=1,2,3,4,…)
