In the first case, the moon (at that phase) is still about three days from being full, and rises about 3 hours before sunset. It would be 45 degrees above the horizon at sunset becasue it rises 15 degrees per hour. Therefore it is sunset, which occur at about 7 PM (Daylight Time) on that equinox date.
In the second case, the sun rises 7 AM daylight time. Almost all of the USA is on Daylight time at autumnal equinox). In waning crescent phase, it sets about 3 hours before sunrise. Because of its 45 degree above west location, it will set in about three hours. So the time is about local sunrise or 7 AM, Daylight Time.
These answers are approximate. Precise times depend upon longitude within the time zone and other factors.
