Using the conversion formula, [tex]{}^{\circ}C = ({}^{\circ}F - 32) \times \frac{5}{9}[/tex], calculate the Celsius equivalent of [tex]77^{\circ}F[/tex].

A. 81
B. 32
C. 25
D. 59.2
E. 212

Answer :

To convert 77°F to Celsius using the formula:

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

Let's go through the steps:

1. Subtract 32 from the Fahrenheit temperature:
[tex]\[
77 - 32 = 45
\][/tex]

2. Multiply the result by [tex]\(\frac{5}{9}\)[/tex]:
[tex]\[
45 \times \frac{5}{9} = 25
\][/tex]

So, 77°F is equal to 25°C.

Therefore, the correct answer is 25.
