If the angle of the first turning is ∠ B at 75 degrees, the angle of the second turning is ∠ C at 110 degrees, and the angle of the third turning is ∠ D, then the road De is just parallel to the road AB before the first turning, then the degree of ∠ D should be_____ degree

There must be a schematic diagram. You must draw it, or there will be two situations
1. 180-（110-75）=145°
2. 110-75=35°

6. There is a section of uphill and a section of level road from a to B. if the uphill is 3km per hour, the level road is 4km per hour, and the downhill is 5km per hour, then it takes 54 minutes to go from a to B and 42 minutes to go from B to A. what is the total distance from a to B? I think the answer is: 54 minutes = 0.9 hours, 42 minutes = 0.7 hours, the time for leveling is x hours. The equation is: 3 (0.9-x) + 4x = 4x + 5 (0.7-x) to get x = 0.4 hours, the whole journey is 3.1 km
