In ΔEFG, \overline{EG} EG is extended through point G to point H, \text{m}\angle EFG = (2x+1)^{\circ}m∠EFG=(2x+1) ∘ , \text{m}\angle FGH = (6x+2)^{\circ}m∠FGH=(6x+2) ∘ , and \text{m}\angle GEF = (x+19)^{\circ}m∠GEF=(x+19) ∘ . Find \text{m}\angle GEF. m∠GEF.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
