Question

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

Answer 1

Adjacent angles of a parallelogram are supplementary.

ATQ,

1x+2x=180

3x=180

x=180/3

x=60

The angles are—

60°, 120°, 60°, 120°

Answer 2

Step-by-step explanation:

sum of the two adjacent angles =180°

the angles in the ratio of 1:2

take as 1x,2x

1x+2x= 180

3x=180

x=60

2x=120°

the two adjacent angles are 60°,120°
