Answer:
18.74 °C.
Step-by-step 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:
So we just have to replace the given data to obtain:
The answer would be 18.74 °C.
