1. **State the problem:** We have an isosceles triangle \(\triangle LMN\) with base \(NL\). The angles are given as \(m \angle N = (2x + 33)^\circ\) and \(m \angle L = (3x + 24)^\circ\). We need to find the degree measure of each angle in the triangle.
2. **Identify the properties:** Since \(\triangle LMN\) is isosceles with base \(NL\), the two sides \(LM\) and \(MN\) are equal. Therefore, the angles opposite these sides are equal. The base angles are \(\angle N\) and \(\angle L\), so \(m \angle N = m \angle L\).
3. **Set up the equation:** Since \(m \angle N = m \angle L\), we have:
$$2x + 33 = 3x + 24$$
4. **Solve for \(x\):**
$$2x + 33 = 3x + 24$$
$$33 - 24 = 3x - 2x$$
$$9 = x$$
5. **Find the angles:** Substitute \(x = 9\) into the expressions for \(\angle N\) and \(\angle L\):
$$m \angle N = 2(9) + 33 = 18 + 33 = 51^\circ$$
$$m \angle L = 3(9) + 24 = 27 + 24 = 51^\circ$$
6. **Find the third angle \(\angle M\):** The sum of angles in a triangle is \(180^\circ\):
$$m \angle M = 180 - (m \angle N + m \angle L) = 180 - (51 + 51) = 180 - 102 = 78^\circ$$
**Final answer:**
\(m \angle L = 51^\circ\)
\(m \angle M = 78^\circ\)
\(m \angle N = 51^\circ\)
