29 degrees C to Fahrenheit.

Shtirlitz [24]

Answer:

29 degrees Celsius are 84.2 Fahrenheit.

Step-by-step explanation:

In order to convert Celsius to Fahrenheit you can use this formula: $F = C * 1.8 + 32$ .

Here we have $F = 29 * 1.8 + 32$ which equals 84.2. Instead of 1.8 you can use the fraction $\frac{9}{5}$ if you wish so.
