Answer:

Angle a = 126°

Step-by-step explanation:

in the given figure,

b = 54°

( since they form vertical opposite angle pair, )

and

a = c

( since they are pair of vertical opposite angles )

now,

we know sum of all these angles = 360°

( because they for complete angle )

so,

=》a + b + c + 54° = 360°

=》a + 54° + a + 54° = 360°

( since, b = 54°, and a = c )

=》2a + 108° = 360°

=》2a = 360° - 108°

=》a = 252° ÷ 2

=》a = 126°
