<reasoning>

Identify the properties of the kite

Using the Kite Properties knowledge point
\[
\angle K \cong \angle M \implies m\angle K = m\angle M = 118^\circ
\]

Verify using the quadrilateral angle sum

Using the Quadrilateral Angle Sum knowledge point
\[

$$\begin{aligned} m\angle J + m\angle K + m\angle L + m\angle M &= 360^\circ \\ 78^\circ + 118^\circ + 46^\circ + 118^\circ &= 360^\circ \\ 360^\circ &= 360^\circ \end{aligned}$$
