The slope of a line is double of the slope of another line. If tangents of the angle between the is find the slopes of the other line.

Text Solution

Verified by Experts

Let m and m1 be the slopes of two given line such that m1=2m.
We know that ` theta` is the angle between the lines l1 and l2 with slopes m1 and m2,
then
` tan theta = | quad (m2-m1) div (1+ m1m2)|` ...
