JEE Main 2024 Mathematics question
A line passing through the point A(9, 0) makes an angle of 30° with the positive direction of x-axis. If this line is rotated about A through an angle of 15° in the clockwise direction, then its equation in the new position is :
Answer: (A)
Solution
The new inclination is 30° − 15° = 15°, with slope tan15° = 2 − √3. The
