Answer: an triangle's angles will always add up to 180 so: 54+82=136 180-136=56 x=56
We also know that vertical angles are the same. (angles across from each other) and that the sum of these 4 angles will be 360. using this, we get 56+56=112 and then we do 360-112=248 248/2=124 So y=124.
I hope this helps.
