The coordinates of the point A are (x, y), where x 0. If the line segment OA (O is the origin) makes an angle of 150 with the positiveX-axis, then by what angle (anticlockwise) should OA be rotated so as to make x positive and ynegative?

1.	The coordinates of the point A are (x, y), where x 0. If the line segment OA (O is the origin) makes an angle of 150 with the positiveX-axis, then by what angle (anticlockwise) should OA be rotated so as to make x positive and ynegative?
Answer» The coordinates of the point A are (x, y), where x<0 and y> 0. If the line segment OA (O is the origin) makes an angle of 150 with the positiveX-axis, then by what angle (anticlockwise) should OA be rotated so as to make x positive and ynegative?
