Answer :

To convert a temperature from Fahrenheit to Celsius, you can use the formula:

[tex]\[ C = (F - 32) \times \frac{5}{9} \][/tex]

where [tex]\( C \)[/tex] is the temperature in Celsius and [tex]\( F \)[/tex] is the temperature in Fahrenheit.

Let's apply this formula to convert [tex]\( 85^\circ F \)[/tex] to Celsius:

1. Start with the temperature in Fahrenheit:
[tex]\[ F = 85 \][/tex]

2. Subtract 32 from the Fahrenheit temperature:
[tex]\[ F - 32 = 85 - 32 = 53 \][/tex]

3. Multiply the result by [tex]\(\frac{5}{9}\)[/tex] to convert to Celsius:
[tex]\[ C = 53 \times \frac{5}{9} \][/tex]

4. Calculate the result:
[tex]\[ C \approx 29.44 \][/tex]

Therefore, [tex]\( 85^\circ F \)[/tex] is approximately [tex]\( 29.44^\circ C \)[/tex].
