Question

In the given figure, ABCD is a parallelogram. Side DC is produced
to E and ZBCE = 105º.
Calculate ZA, ZB, ZC and ZD.​

Answer 1

Abe yeh Z kya hai?? Bhai its not mentioned

Answer 2

Answer:

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

so, angle BCD= 180- 105

angle BCD =75° or angle C =75°

and angle A = angle BCD (opposite angles of parallelogram are equal)

so, angle A = 75°

angle D =angle BCE ( corresponding angles)

so, angle D = 105°

now , angle B= angle D (opposite angles of parallelogram are equal)

so, angle B = 105°
