Because the values of circular functions repeat every \( 2 \pi \) , they are used to describe things that repeat periodically. For example, the maximum afternoon temperature in a given city might be modeled by the formula below. In the formula, t represents the maximum afternoon temperature in month \( x \) , with \( x = 0 \) representing January, \( x = 1 \) representing February, and so on. 

\( t = 15 - 10 \cos \frac { x \pi } { 6 } \) 

The maximum afternoon temperature in January is ___. (Round to the nearest integer as needed.)
