Respuesta :

It should be 98, as A = C and B= D

Answer:

∠A=98

Step-by-step explanation:

The properties of a parallelogram says that , the opposite interior angles of a parallelogram are equal. Hence the measurement of ∠C is equal to ∠A and ∠D is equal to ∠B. Hence ∠A=98°

Also ∠D=180°-∠C, ∠C=98° , Hence ∠D=180°-98°=82°

and  ∠B=180°-∠C , ∠B=180°-98°=82°

These are called supplementary angles as there sum is 180°
