Question

the measures of two adjacent angles of a parallelogram are the in the ratio 2 is to 7 find the measures of each angle of the parallelogram​

Answer 1

Let the ratio be x so the adjacent angle is ,2x and 7x

according to question

7x + 2x= 180(sum of interior angle = 180°)

so

9x = 180

x = 20

40 and 140 is the two angle

Answer 2

Answer:

let the angles be 2x and 7x

now

we know that sum of adjacent angles of a parallelogram is 180°

therefore

2x+7x=180

9x=180

x=180/8

x=20

ist angle is 40°

2nd angle is 140°
