Find the angle between the lines whose slopes are

Question

Question

Answer 1

CONCEPT:

If α is the acute angle between two non-vertical and non-perpendicular lines L₁ and L₂ with slopes m₁ and m₂ respectively then

CALCULATION:

Here, we have to find the angle between the lines whose slopes are

Let

As we know that,

⇒

⇒ α = 30°

So, the angle between the lines whose slopes are is 45°

Hence, option C is the correct answer.
