Mathematics (NDA) Coordinate Geometry

The angle between the lines x + y – 3 = 0 and x – y + 3 = 0 is α and the acute angle between the lines x – $\sqrt{3}$ y + 2 $\sqrt{3}$ = 0 and $\sqrt{3}$ x – y + 1 = 0 is $\beta$ , Which one of the following is correct ?

$\alpha=\beta$

$\alpha>\beta$

$\alpha<\beta$

$\alpha=2\beta$

Explanation:

$\angle$ between x + y – 3 = 0 & x – y + 3 = 0 is 90°
=> α = 90°
As, $\beta$ is acute, therefore $\alpha>\beta$
