Answer:
m∠Z = 23°
Explanation:
We are given that the two triangles are congruent. This means that their corresponding side lengths and angle measurements are equal.
m∠N = m∠Y, m∠X = m∠M, m∠Z = m∠L.
Any triangle's angles sum to 180°
m∠Z + m∠Y + m∠X = 180°
m∠Z + 124° + 33° = 180°
m∠Z = (180-124-33)°
m∠Z = 23°
