Question 199925
Sorry,  but  we  need  to  see the  angles  to  pick  proof
.
You  might  be  able  to  resolve  yourself  if  you,,,,look  at  the  two  angles,,,are  they  on  "same  side"  or  "alternate  sides"  of  the  transversal.  Now,  are  the  angles  between  the  parallel  lines, " interior",  or outside  the  parallel  lines,,"exterior".  
.
if  you  can  define  these  criteria,  you  might  pick  the  right  answer,
.
good  luck
