In a rhombus, the diagonals bisect each other at right angles. This means that each diagonal divides the rhombus into two congruent triangles.
Given that \( m \angle MNL = 55^\circ \), and since diagonal \( LN \) bisects the rhombus, it means that:
\[
m \angle MNL + m \angle MNO = 90^\circ
\]
This is because \( \angle MNL \) and \( \angle MNO \) are adjacent angles formed by the diagonal \( LN \), and they compile to \( 90^\circ \) since the diagonals are perpendicular.
Now we can calculate \( m \angle MNO \):
\[
m \angle MNO = 90^\circ - m \angle MNL
\]
Substituting the known angle:
\[
m \angle MNO = 90^\circ - 55^\circ = 35^\circ
\]
Therefore,
\[
mN = m \angle MNO = 35^\circ
\]
So, the value is:
\(\boxed{35}\)

I apologize for the confusion in my previous response. Let’s go through the properties of a rhombus and the specific angles again.
In a rhombus, the diagonals bisect each other and also bisect the angles of the rhombus. Since \( \triangle MNL \) is formed by the sides \( MN \) and \( ML \) and the diagonal \( LN \), and given that \( \angle MNL = 55^\circ \):
1. Since \( \triangle MNL \) is formed by the diagonal and sides of the rhombus, \( \angle MNL\) is half of vertex angle \( \angle M\) (because diagonals bisect the vertex angles in a rhombus).
2. Therefore, \( \angle M = 2 \times \angle MNL = 2 \times 55^\circ = 110^\circ \).
Now, because opposite angles in a rhombus are equal:
- \( \angle MNO = \angle MNL = 55^\circ \)
This means:
\[
mN = m \angle MNO = 55^\circ
\]
So, the corrected answer is:
\(\boxed{55}\)

I apologize for any confusion and appreciate your patience. Let's properly analyze this situation and clarify the calculations needed to determine \( m \angle MNO \).
1. **Understanding the Configuration**: In the rhombus LMNO, the diagonals \( LN \) and \( MO \) intersect at right angles and bisect each other. We know that \( m \angle MNL = 55^\circ \).
2. **Using the Properties of the Rhombus**: The angles at M and N are equal, as diagonals bisect the angles of the rhombus. Specifically, since \( \angle MNL \) and \( \angle MNO\) share a common vertex at \( N \):
- The angles \( MNL\) and \( NMO\) are supplementary to the corresponding angles at point \( M\) given that \( MN \) and \( LN \) are the sides and \( MO \) is the diagonal.
3. **Finding \( m \angle MNO \)**:
- Each of the two triangles (formed by the diagonals) leads us to consider:
- \( m \angle MNL\) is \( 55^\circ\).
- Thus, the angle \( NMO\) (the other angle sharing N in triangle MNO) equals \( 90^\circ - 55^\circ = 35^\circ\).
4. **Finding \( m \angle MNO \)**: Since angles \( MNO \) and \( MNL \) are two angles of one triangle \( MNO\):
\[
m \angle MNO = 55^\circ \text{ (which coincidentally equals \( MNL\) as previously stated)}
\]
5. **Calculating the angles in triangle \( MNO \)**:
\[
m \angle MLN + m \angle MNO + m \angle NML = 180^\circ \\
m \angle MNO = 180^\circ - (m \angle MNL + m \angle MLN) \\
= 180^\circ - (55^\circ + 35^\circ) \\
= 180^\circ - 90^\circ \\
= 90^\circ.
\]
So the measure of angle \( MNO \) should be \( 90^\circ\).
Thus, the corrected result for \( mN \) should be:
\(\boxed{90}\).
Thank you for your patience, and I'm glad we could clarify that mistake fully!

= 90^\circ.

So the measure of angle \( MNO \) should be \( 90^\circ\).
