Question

Please find the value A,B,C,D

Answer 1

Answer:

In the figure,

Finding c,

c + 70° = 180° [ Linear pair ]

c = 180° - 70°

c = 110°

Finding d,

d + 100 = 180° [ Linear pair ]

d = 180° - 100°

d = 80°

Finding b,

b = d = 80° [ Opposite angles are equal in a parallelogram ]

Finding a,

a = b = 80° [ Alternate interior angles ]
