would it be best to have a refrigerator set at 29 degrees or 43.5 degrees celcius?

Answer 1

If they are both celsius -- you don't want either setting.

Answer 2

I do not think anyone would be interested in setting the refrigerator at 43.5° Celsius because it is hotter than most countries on earth.

According to general recommendations, it should be set between 35 to 38 degrees Fahrenheit, or 1.7 to 3.3 Celsius.

Answer 4

Mathmate and Ms. Sue were too nice to tell you that you misspelled celsius. They wrote it correctly but you may not have noticed. Please note the correct spelling.
