Answer:
40 degrees
Explanation:
if the lines are perpendicular, then they are also sharing the same line so that means, its a simple equation of 180-140=40.
The value of angle 2 = 40°
Given : angle 1 = 140°
angle 1 + angle 2 = 180° { because they are linear pair }
=> 140 + angle 2 = 180°
=> angle 2 = 180 - 140
=> angle 2 = 40°
