Given:
A 7-pointed star, the ant must repeat the two steps 7 times, the ant makes 2 complete revolutions.
To find:
The angle A
Solution:
From given, we have,
An ant must repeat the two steps 7 times and ant makes 2 complete revolutions
For a complete revolution, the angle made is 360°
Similarly, for 2 complete revolutions, the angle made is 2 × 360° = 720°
The number of steps taken by an ant = 7
Thus, each angle = 720°/7 = 102.857
Therefore, angle A = 102.9°
