Answer:
110
Step-by-step explanation:
lets assume y is the angle next to x which should complete to form a 360.
50 + 25 + 35 + y = 360
y = 250
x + y = 360
x + 250 = 360
x = 110
I believe it is x=55. I could be wrong lol
The answer would be x = -7.
Hope this helps!
I believe the answer is (a+c, b) but I'd double check to make sure.
