STEP 1

1. The angle $\angle \mathrm{LMN}$ is formed by the intersection of lines $\mathrm{LM}$ and $\mathrm{MN}$.
2. The lines $\mathrm{LM}$ and $\mathrm{MN}$ are perpendicular to each other.
3. A right angle measures $90^\circ$.

STEP 2

1. Identify the type of angle formed.
2. Determine the measure of the angle.

STEP 3

Identify the type of angle formed by the lines $\mathrm{LM}$ and $\mathrm{MN}$. Since the lines are described as vertical and horizontal, they intersect perpendicularly.

Determine the measure of the angle. A perpendicular intersection forms a right angle, which measures $90^\circ$.
The measure of $\angle \mathrm{LMN}$ is:
$$\boxed{90^\circ}$$
