Answer :
Answer:
18.74 °C.
Explanation:
Measurements => Temperature and Temperature Scales.
Temperature is a measure of the average kinetic energy of the particles in matter. Currently, we use temperature scales such as °C (Celsius), °F (Fahrenheit), and K (Kelvin).
In this case, we have to convert 65.74 °F to °C, so the formula to convert °F to °C is the following:
[tex]°C=\frac{°F-32}{1.8}.[/tex]So we just have to replace the given data to obtain:
[tex]\begin{gathered} °C=\frac{65.74-32}{1.8}, \\ \\ °C=18.74\text{ \degree C.} \end{gathered}[/tex]The answer would be 18.74 °C.
