I am facing east. I turn 100° in the clockwise direction and then 155° in the anticlockwise direction. Which direction I am facing now?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → North-east
Directions are measured clockwise from North: North 0°, East 90°, South 180°, West 270°. A clockwise turn adds to this angle and an anticlockwise turn subtracts from it.
Start: facing East, 90°
After 100° clockwise: \(90^\circ+100^\circ=190^\circ\), that is, 10° past South towards West
After 155° anticlockwise: \(190^\circ-155^\circ=35^\circ\), that is, 35° from North towards East
A direction between North and East is North-east.
