To convert 20°C to degrees Fahrenheit using the formula \( F = \frac{9}{5}C + 32 \):
-
Substitute \( C = 20 \) into the equation: \[ F = \frac{9}{5} \times 20 + 32 \]
-
Calculate \( \frac{9}{5} \times 20 \): \[ F = 36 + 32 \]
-
Now add 32: \[ F = 68 \]
Therefore, the temperature in degrees Fahrenheit is \( \boxed{68} \).
