Two Parallel lines , an angle between them
Two crossed lines. Find angle ADE
Two consecutive angles sum up an angle of 180 degrees
Mesurement of angle First find angle C = 180 - 150 = 30 °
hen Then find angle E = 180 - 45 - 30 = 110°
Now angle A = Angle F = 180° -150°= 30° ( because there are 2 parallel lines)
Now finally find angle D = 180° - 110° - 30° = 40 °
Angle D = 40 degrees
