The correct answer is $84$. The sum of the measures of the interior angles of a triangle is $180°$. It's given that in triangle $JKL$, the measures of $\angle K$and $\angle L$ are each $48°$. Adding the measures, in degrees, of $\angle K$ and $\angle L$ gives $48+48$, or $96$. Therefore, the measure of $\angle J$, in degrees, is $180-96$, or $84$.
