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 .
