ANSWER
[tex]13.9°C[/tex]
EXPLANATION
We want to convert 57°F to degrees Celsius.
To do this, apply the formula:
[tex]C=\frac{5}{9}(F-32)[/tex]
where F = temperature in Fahrenheit
Therefore, 57°F to degrees Celsius is:
[tex]\begin{gathered} C=\frac{5}{9}(57-32) \\ \\ C=\frac{5}{9}*25 \\ \\ C=13.9°C \end{gathered}[/tex]
That is the answer.
