To convert the temperature from Fahrenheit to Celsius using the formula [tex]\( T_{\left( {}^{\circ} C \right)} = \left( T_{\left( {}^{\circ} F \right)} - 32 \right) \times \frac{5}{9} \)[/tex], follow these steps:
1. Identify the initial temperature in Fahrenheit: In this case, the given temperature is [tex]\( 77^{\circ} F \)[/tex].
2. Subtract 32 from the Fahrenheit temperature:
[tex]\[
77 - 32 = 45
\][/tex]
3. Multiply the result by [tex]\(\frac{5}{9}\)[/tex]:
[tex]\[
45 \times \frac{5}{9} = 45 \times 0.5555\ldots = 25
\][/tex]
So, the temperature equivalent to [tex]\( 77^{\circ} F \)[/tex] is [tex]\( 25^{\circ} C \)[/tex].
Therefore, the answer is:
[tex]\[
25^{\circ} C
\][/tex]
