Question

find the acute angle between lines
having slopes - 4 and 2​

Answer 1

Answer:

how much we are not a good I was

Answer 2

Explanation:

Let us consider the acute angles between the lines to be Ф.

If the two slopes are considered as m and m'.

So, tan Ф = (m - m')/[(1 + mm')]

Here, m = -2 and m' = 3

So, tan Ф = (-2 - 3)/[(1 - 6)] = -5/-5 = 1

Ф = tan⁻¹ (1)

= 45°

This is the subtended angle.
