Respuesta :

None, the last choice since the angles given only relate to one common large angle.

Answer:

option C

Step-by-step explanation:

In the figure attached, the given quadrilateral will be parallelogram if the given angles ∠7 = ∠3 and ∠8 = ∠4 ( alternate angles ) or ∠1 = ∠5 and ∠2 = ∠6 ( alternate angle )

But the given angles are ∠7 and ∠8 which represent a big angle A when combined.

Therefore, option C  none will be the answer.
