Respuesta :

The sum of the adjacent angles of a parallelogram is equal to 180° . Let the adjacent angle be x . The opposite angles of a parallelogram are equal. Therefore, rest of the angles are 40°, 140° and 140°.

Answer:

Angles ⇒ 40°, 40°, 140°, 140°

Step-by-step explanation:

Since the opposite angles of a parallelogram are equal, and the angles in a quadrilateral add up to 360°:

360 - 2(40) = 280

280/2 = 140°

Angles ⇒ 40°, 40°, 140°, 140°
