Question

Lines AD and BC are parallel. What is the angle measurement of Angle ADEPoint D)?А45150°Bfс

Answer 1

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
