x \cos \beta+y \sin \beta=\frac{5 \pi}{2}

and

x \cos \alpha+y \sin \alpha=\frac{\pi}{2}

View answer and explanation

Correct option: D

|\beta-\alpha|

Option D (

|\beta-\alpha|

) is correct because it represents the absolute difference between the angles, which gives the acute angle between the lines.
