Write the angle in decimal degrees. \( 31^{\circ} 42^{\prime} \) \( 31^{\circ} 42^{\prime}=\square^{\circ} \) (Type an integer or an exact decimal. If the decimal does not terminate, round to the nearest hundredth.)

To convert \( 31^{\circ} 42^{\prime} \) into decimal degrees, you'll need to convert the minutes into a fraction of a degree. Since there are 60 minutes in a degree, you can calculate: \[ 42^{\prime} = \frac{42}{60} = 0.7 \] Now, add this to the 31 degrees: \[ 31^{\circ} + 0.7^{\circ} = 31.7^{\circ} \] Therefore, the final answer is \( 31.70^{\circ} \).
