If the direction cosines of a line are ( {ab}, {b}, b) and the angle between line and {x} -axis is \frac{\pi}{3} then a pair of possible values for a, b are {L}' are ( {ab}, {b}, b) and the angle between line '{L}' and {x} -axis is {π}/{3} then a pair of possible values for a, b are {L}' and {x} -axis is {π}/{3} then a pair of possible values for a, b are {L}' are ( {ab}, {b}, b) and the angle between line '{L}' and {x} -axis is {π}/{3} then a pair of possible values for a, b are

Correct Answer is : √23,√38
