In triangle \( \Delta LMN \), since it is isosceles with \( \angle M \cong \angle L \), we have:

  • \( m\angle L = m\angle M = 36^\circ \)

To find the measure of angle \( N \), we can use the triangle sum property, which states that the sum of the angles in a triangle is always \( 180^\circ \).

So, we can write the equation:

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

Substituting the known values:

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

This simplifies to:

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

Now, subtract \( 72^\circ \) from both sides:

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

Thus, we find the measures of the angles:

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

In conclusion:

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