Verified step by step guidance

Start with the formula to convert Fahrenheit to Celsius: \( C = \frac{5}{9} (F - 32) \).

Substitute the given Fahrenheit temperature into the formula: \( C = \frac{5}{9} (89 - 32) \).

Calculate the difference inside the parentheses: \( 89 - 32 = 57 \).

Multiply the result by \( \frac{5}{9} \): \( C = \frac{5}{9} \times 57 \).

Perform the multiplication to find the temperature in Celsius.
