Given:
The equations of the lines are
x − 4y = 3 … (1)
6x − y = 11 … (2)
To find:
Angles between two lines.
Explanation:
Let m1 and m2 be the slopes of these lines.
m1 = \(\frac{1}{4}\), m2 = 6
Let θ be the angle between the lines. Then,
Hence, the acute angle between the lines is tan-1 \(\Big(\frac{23}{10}\Big)\)
