Question

If the ratio of measures of two adjacent angles of a parallelogram is 1:2 find the measures of all angles of parallelogram

Answer 1

Answer: 60,120,60,120

Step-by-step explanation:

Adjacent angle sum of parallelogram = 180

1x + 2x = 180

3x = 180

x = 60

Hence angles are:

60,120,60,120

[opposite angles of a parallelogram are equal]
