The Slope of a Line is Double of the Slope of Another Line. If Tangent of the Angle Between Them is 1/3, Find the Slopes of He Lines - Mathematics

The slope of a line is double of the slope of another line. If tangent of the angle between them is 1/3, find the slopes of the lines

Solution

Let m_1 and m be the slopes of the two given lines such that m_1 =2m

We know that if θisthe angle between the lines l1 and l2 with slopes m1 and m2, then

Is there an error in this question or solution?
