Question

In a parallelogram ABCD, \B=100°..Find \A and \D​

Answer 1

Answer:

Angle A=80°

Angle D=100°

Step-by-step explanation:

angle B= angle D ( opposite angles in a parallelogram are equal)

therefore,

angle D = 100°

Angle D+ Angle A=180° ( adjacent angles of a parallelogram are suplementary)

angle A + 100°=180°

angle A= 180° - 100°

angle A=80°
