Answer:
(-5,-1)
Step-by-step explanation:
u = ((-7-3),(5-9))
u = (-10,-4)
v = ((6-1),-1-(-4))
v = (5,3)
u + v = (-10,-4)+(5,3)
u + V = (-5,-1)
⟨-5, -1⟩

x=80
The sum of interior angles in a quadrilateral is 360°
the square represents a right angle= 90 degrees
124+66+90=280
360-280=80
(-4+2*2)+8
2*2=4
-4+4= 0
0+8= -8
