Question

# The angle between the lines x and x cos where is

## The correct answer is:

### We should find the angle between two straight lines

$xcosα+ysinα=p_{1}$

$slope=m_{1}=sinα−cosα =−cotα$

And $xcosβ+ysinβ=p_{2}$

$slope=m_{2}=sinβ−cosβ =−cotβ$

Therefore,

$tanθ=∣tan(α−β)∣$

$⇒θ=α−β$

Hence θ=α−β
