In triangle \( \triangle LMN \), since it is isosceles with \( \angle M \cong \angle L \) and given that \( m\angle L = 36^\circ \), it follows that:

\[ m\angle M = 36^\circ \]

Now, to find \( m\angle N \), we can use the fact that the sum of the angles in any triangle is \( 180^\circ \). Thus,

\[ m\angle L + m\angle M + m\angle N = 180^\circ \]

Substituting the known values:

\[ 36^\circ + 36^\circ + m\angle N = 180^\circ \]

This simplifies to:

\[ 72^\circ + m\angle N = 180^\circ \]

To solve for \( m\angle N \), subtract \( 72^\circ \) from \( 180^\circ \):

\[ m\angle N = 180^\circ - 72^\circ = 108^\circ \]

Therefore, the measures of the angles are:

\[ m\angle M = 36^\circ \quad \text{and} \quad m\angle N = 108^\circ \]

Final results:

  • \( m\angle M = 36^\circ \)
  • \( m\angle N = 108^\circ \)
