We are given a circle with center $T$. $NL$ and $MK$ are diameters of circle $T$. In Part A, we need to identify whether arc $LKM$ is a major arc, minor arc, or semicircle, and then find its measure. In Part B, the diagram is the same as in Part A but there is no task associated.

1. Problem Description

We are given a circle with center $T$. $NL$ and $MK$ are diameters of circle $T$.

In Part A, we need to identify whether arc $LKM$ is a major arc, minor arc, or semicircle, and then find its measure.

In Part B, the diagram is the same as in Part A but there is no task associated.

2. Solution Steps

For Part A:

The measure of an arc is equal to the measure of its central angle. The measure of a full circle is $360^{\circ}$. A semicircle has a measure of $180^{\circ}$. A minor arc has a measure less than $180^{\circ}$, and a major arc has a measure greater than $180^{\circ}$.

The central angle of arc $LK$ is $48^{\circ}$, and the central angle of arc $KJ$ is $44^{\circ}$. Since $MK$ is a diameter, arc $MK$ is a semicircle, and its measure is $180^{\circ}$. Thus, the measure of arc $LM$ is $180^{\circ} - 48^{\circ} = 132^{\circ}$, and the measure of arc $JM$ is $180^{\circ} - 44^{\circ} = 136^{\circ}$.

The measure of arc $LKM$ is the sum of the measures of arcs $LK$ and $KM$. Since $KM$ is a semicircle, the measure of arc $KM$ is $180^{\circ}$. The measure of arc $LK$ is $48^{\circ}$.

Therefore, the measure of arc $LKM$ is $180^{\circ} + 48^{\circ} = 228^{\circ}$. Since $228^{\circ} > 180^{\circ}$, arc $LKM$ is a major arc.

3. Final Answer

For Part A:

Arc $LKM$ is a major arc.

The measure of arc $LKM$ is $228^{\circ}$.
