Answer:
160
Step-by-step explanation:
As the moon's diameter is straight, the distance from the observer to the moon and the diameter are at 90°, subtending an angle at the viewer's eye. This is:
tan∅ = diameter / distance
tan∅ = 2160 / 238,860
∅ = 0.52°
Monday: 63.8
Tuesday: 63.8 + 25.3 = 89.1
Wednesday: 89.1 + 14.5 = 103.6
63.8 + 89.1 + 103.6 = 256.5
