What angle?
I turn 40 degrees clockwise, 70 degrees anticlockwise and finally 90 degrees clockwise. If I want to return to my original position by turning through the smallest possible angle, in which direction should I turn and what should the angle be?
We can have clockwise as positive and anticlockwise as negative.
ReplyDeleteThen we get:
40-70+90 = 60
This means that the angle should be 60 degrees clockwise
