The triangle is iscosceles where angle A  = angle B

 

So

 

34  =  x  - 5      add 5 to both sides

 

39° = x  .....so angle B  also equals  34°  

 

So

 

34 + 34 +  4y  = 180

 

68 + 4y   =  180       subtract 68 from both sides

 

4y  = 112            divide both sides by  4

 

y  =  112 / 4  =    28

 

Edit to correct an idiotic error....LOL!!!!!
