All internal angles in a quadrilateral add to 360
so
x+110+110+70=360
x+290=360
minus 290 both sides
x=70 degrees
Answer:
B. -10
Step-by-step explanation:

The first one has got a result different from -12 or -10
It would be 5180 for the answer
3(y-9)-y=7
3y - 27 -y = 7
2y = 34
Y = 17
3(x) -17 = 7
3x = 24
X = 8
