Answer:
angle 4 = 56°
Step-by-step explanation:
Interior angles in the same side of the transversal are supplementary (their sum is 180°)
Angle 1 and 4 are interior angles on the same side of the transversal.
So, angle 1 + angle 4 = 180°
Angle 1 = 124° (given)
124 + angle 4 = 180°
angle 4 = 180° - 124° = 56°
Therefore, angle 4 = 56°
