Question
Find the approximate angle of rotation.
- 60°
- 100°
- 150°
- 180°
Hint:
if the angle is not just straight but it leans towards the line it is always less than 90 degree .
The correct answer is: 60°
From observation, the angle of rotation is 60°.
As , one line is just not straight over the other so it is not 90 and it is leaning towards line so , it must be less than 90 and greater than 0 , so 60 is best fit choice here .
