Question
Find the approximate angle of rotation.
- 60°
- 100°
- 90°
- 180°
Hint:
one line over other means 90 and below means 270 .
The correct answer is: 90°
From observation, the angle of rotation is 90°.
as it is clear from picture, whenever one line is just over the other it must be 90 degrees.
