Explanation:
______________________________________________________

From the "image attached",  note that:

           "139" and "y" ; together; form a "straight line" ; 

→  that is:  "139" and "y" are supplementary ; 

 and by definition;  "supplementary angles"  add up to " 180 degrees" ; 
______________________________________________________
   
      →  y + 139 = 180  ;  Solve for "y" ; 

Subtract " 139 "  from each side of the equation;  
           to isolate "y" on one side of the equation; & to solve for "y" ; 

     →   y +  139 − 139 = 180 − 139 ; 

to get:

     →   y = 41 degrees:
