The temperature in degrees Celsius is $\left( {}^\circ C \right)=22.22{}^\circ $.

Work Step by Step

The temperature in degrees Celsius $\left( {}^\circ C \right)$ can be calculated using the formula, ${}^\circ C=\left( {}^\circ F-32 \right)\frac{5}{9}$, Therefore, substitute the value of ${}^\circ F$ as 72 in the formula, $\begin{align} & {}^\circ C=\left( {}^\circ F-32 \right)\frac{5}{9} \\ & =\left( 72-32 \right)\frac{5}{9} \\ & =\left( 40 \right)\frac{5}{9} \\ & =22.2{}^\circ \end{align}$
