Answer is C) 51

Angle y is 62 degrees because it forms a straight line with the angles next to it (57 and 61) so angle y must be 62.

There are 180 degrees in a triangle so 180-62-67 = 51
The answer would be C. 51 degrees 
 
57+61= 118
118-180= 62
62+67+x= 129x
129x = 180
x = 51

I hope this helped! : )
