To convert the temperature from degrees Celsius to degrees Fahrenheit using the formula \( F = 9/5 \times C + 32 \), we start with the given temperature in Celsius.
Given: \( C = 30 \)
Now, substitute that into the formula:
\[ F = 9/5 \times 30 + 32 \]
First, calculate \( 9/5 \times 30 \): \[ 9/5 \times 30 = 54 \]
Now add 32: \[ F = 54 + 32 = 86 \]
Therefore, the temperature in degrees Fahrenheit is: \[ \boxed{86} , \text{°F} \]
