ABCD is a quadrilateral in which AB//DC and angleAD//BC find angle B , angle c and angle D​

Answer 1

hey mate
good morning
here's the answer
hope it helps you

Answer 2

ABCD is a parallelogram.
hence opposite angles are equal......(1)

angle A + angle B = 180 (sum of angles of the corresponding sides of a parallelogram is 180°)

50° + B = 180°

B = 180°-50°

B = 130°

angle C = angle A.....from(1)
angle C = 50°

angle D = angle B.....from(1)
angle D = 130°

therefore angle,

B = 150°

C = 50°

D =150°
