according to the question
l//m
and angle 1 = 78 degree
so, angle 1 = angle 3
because l//m
angle 2 and angle 3 forming a linear pair
angle 3 + angle 2 = 180 degree
78 degree + angle 2 = 180
angle 2 = 180-78
= 102 degree
hence the measure of angle 2 is 102 degree.
hope this helps.
Plz mark it as brainliest.
