$\huge{\green}\fcolorbox{yellow}{b}{\underline{\color{red}{Answer}}}$

Step-by-step explanation:

A pair of vertically opposite angles are always equal to each other.

Also, a vertical angle and its adjacent angle are supplementary angles,

i.e., they add up to 180 degrees.

For example,

if two lines intersect and make an angle, say X=45°,

then its opposite angle is also equal to 45°.

And the angle adjacent to angle X will be equal to 180 – 45 = 135°.
