That statement is false.
Angle e= angle g + angle h
As the moon's diameter is straight, the distance from the observer to the moon and the diameter are at 90°, subtending an angle at the viewer's eye. This is:
tan∅ = diameter / distance
tan∅ = 2160 / 238,860
∅ = 0.52°
f(x) = 7x + 13
f(-3) = 7(-3) + 13
f(-3) = -21 + 13
f(-3) = -8
C) work was required by an outside force.
Opposites attract, while same sides repel. This means that two South Pole ends would repel unless they were pushed together by an outside force.
