Question

angle of a parallelogram
is double than its adjacent angle. Find
the measure of all its angles.​

Answer 1

Answer:

Let the two adjacent angles be x° and 2x° . In a parallelogram, sum of the adjacent angles are 180°. Thus , the two adjacent angles are 120° and 60°. Hence, the angles of the parallelogram are 120°, 60°, 120° and 60°

Answer 2

Answer:

Let the two adjacent angles be x° and 2x° . In a parallelogram, sum of the adjacent angles are 180°. Thus , the two adjacent angles are 120° and 60°. Hence, the angles of the parallelogram are 120°, 60°, 120° and 60°.
