Answer:
angle B = 50°
because it is corresponding angles
angle A = angle B ( because they are vertically opposite angles )
so angle A = 50°
angle C + 50° = 180° ( because adjacent sides are supplementary angles )
so, angle C = 180° - 50° = 130°
angle C and angle D are supplementary angles so,
angle C + angle D = 180°
130° + angle D = 180°
angle D = 180° - 130°
angle D = 50°
