both september and march because they both contain equinoxes which is when the sun is at the highest altitude
That completely depends on your latitude ... where you are on earth north or south relative to the equator. -- If your latitude is 23.5° south ... on the Tropic of Capricorn ... the noon sun is directly overhead on December 21. -- If you are more than 23.5° south of the equator, then the noon sun is (113.5° - your south latitude) above the northern horizon. -- If you are between the equator and 23.5° south latitude, the noon sun is (66.5° + your south latitude) above the southern horizon. -- If you are north of the equator, the noon sun is (66.5° - your north latitude) above the southern horizon. Notice that this means that anywhere north of 66.5° north latitude ... the Arctic Circle ... the sun doesn't rise at all on that day, even at noon.
For an observer at latitude 35 degrees, the highest the sun can ever be in his sky is roughly 31.5 degrees above the horizon.
At the autumnal equinox, the Sun is directly over the equator, so the Earth's axial tilt would be an irrelevant data point. Champaign-Urbana, IL is at 40 degrees 7 minutes north latitude, so the "local apparent noon" elevation of the Sun would be 49 degrees 53 minutes. If you were asking this question about the summer solstice, then the Earth's axial tilt would become relevant. If this was 40 degrees, then the Sun would be essentially directly overhead at noon.
The sun's path is highest in the sky at noon on June 21 at this location, indicating the summer solstice when the sun reaches its highest point in the sky.
On the Summer Solstice, June 21, the Sun is at about 23.5 degrees north. If you are at 50 degrees north, then at noon ("Local Apparent Noon", when the Sun reaches its highest point in the sky) on June 21, the Sun will be at an altitude of 66.5 degrees above the southern horizon.
47 degrees.
First, we need the "transit altitude" of the celestial equator, at 80 degrees north. That's 90 - 80 degrees = 10 degrees. At noon (local apparent noon) the Sun's altitude will be: 10 degrees + the Sun's declination. That's the altitude of the Sun's "upper culmination". At "midnight" (the Sun's "lower culmination") the Sun's altitude will be: the Sun's declination - 10 degrees. So, the difference in altitude is 20 degrees. The Sun is 20 degrees higher at noon.
the tilt goes towards the sun, the seasons chang from winter to summer
Your position is 45 degrees latitude north. The altitude of Polaris (the North Star) corresponds to your latitude in the Northern Hemisphere. Since your local noon occurs at 7pm Greenwich Mean Time, you are located in the time zone that is 5 hours behind GMT, such as Eastern Standard Time in the USA.

On June 21, the summer solstice in the Northern Hemisphere, the sun reaches its highest point in the sky. At the equator, the sun will be directly overhead at noon, resulting in an altitude of 90 degrees. This phenomenon occurs because the sun's rays are perpendicular to the equator on this date.
Both
The vertical ray of the sun will strike near the Tropic of Cancer, which is approximately 23.5 degrees north latitude on June 12 at noon. This occurrence is known as the summer solstice in the Northern Hemisphere.
Just about anywhere in the southern hemisphere you can see the sun in the north.
The observer must be 15.5 degrees south of the Arctic circle, so 51.1 degrees north approximately.
