Find the midpoint:
m= x1+x2/2; y1+y2/2
m= 9+-1/2; 8+-2/2
m= 8/2; 6/2
m= (4,3)
(4,3) is your answer.
I hope this helps!

Answer:
The answer is B: 468.50
Step-by-step explanation:
x = 130 is your answer
130 - 20 = 110
Since line E and F are parallel and are straight lines, we know both angles will add up to 180°
110 + 70 = 180
