Hey there!!
We know :-
Angles 27x+4 and 8x+1 sum up to become 180 and angles 8x+1 and y+10 are equal.
... 27x+4+8x+1 = 180
... 35x + 5 = 180
... 35x = 175
... x = 175 / 35
... x = 5
Now,
... 8x + 1
... 8 ( 5 ) + 1
... 40 + 1
... 41
Hence,
... y + 10 = 41
... y = 31
Hence, the value of y is 31.
Hope it helps!
