Answer:
60°
Explanation:
The fairy wheel is circular in nature. We need to note that sum total of angle in a circle is 360°
If we know that the chairs are evenly spaced around, then the angle between two adjacent chairs must be equal all round.
Angle between two Adjacent chair = sum total of angles in the circle/total number of chairs = 360/12
= 30°
Angle between ferris chair B and D will be angle between B and C + angle between C and D
= 30°+30°
= 60°
