Vertical Angle theorem: It is about the angles that are opposite to each other.
Also, vertical angle are congruent that means vertical angles are equal.
In the given figure;
and
are vertical angle
then, by vertical angle theorem,
.
Supplementary angle: the sum of the angles whose measure on the straight line is 180 degree.
From the figure,
,
and
forms a straight line.
then, by the definition of Supplementary angle;

Substituting the value of
in above equation:
or

Simplify:

therefore,
and
,
the value of
.
