Answer:
Midpoint of a line segment with the endpoints A(a1, a2), B(b1, b2) is M(1/2*(a1 + b1), 1/2*(a2 + b2))
So,
(1/2*(-4 + 7), 1/2*(-3 + (-5))) = (1/2*3, 1/2*(-8)) = (1.5, -4)
Answer D is correct.

Answer:
214
Step-by-step explanation:
A circle is 360 degrees
Arc EF is 146 degrees
EF + EDF = full circle
146 + EDF = 360
Subtract 146 from each side
146-146 +EDF = 360-146
EDF =214
A whole turn is 360° so to turn 40° clockwise is equivalent to turn 320° counterclockwise.
