Final answer:
Today's high temperature of 77°F converts to 25°C when using the formula C = (F - 32) ÷ 1.8.
Step-by-step explanation:
To answer the question regarding the conversion of today's high temperature of 77°F to degrees Celsius, we need to use the provided equation C = (°F - 32) ÷ 1.8. Applying this equation:
C = (77 - 32) ÷ 1.8 = 45 ÷ 1.8 = 25°C
Therefore, today's high temperature in degrees Celsius is 25°C, which corresponds to answer choice D.
