Answer 2

Answer:

Step-by-step explanation:

let ABCD be the parallelogram

and ∠BCE=100°

now

∠BCE+∠BCD=180°                            (linear pair)

100°+∠BCD=180°

∠BCD=80°

∠BCD=∠BAD=80°                              (opposite angles)

now ∠BCE=∠ADC=100°                     (corresponding angles)

so, ∠ADC=∠ABC=100°                       (opposite angles)

so, ∠ABC=∠ADC=100°  and ∠BAD=∠BCD=80°
