Question

8. The ratio of two adjacent angles of parallelogram is 11:25, measures of those angle
​

Answer 1

sum of adjacent angles = 180°

25x+11x = 180

36x = 180

x=5

25x = 125

11x= 55

Answer 2

let,

the first adjacent angles is 11 x

and the second adjacent angles be 25 x

According to question

the sum of two adjacent angles of a parallelogram = 180°

11x + 25x =180°

36x =180°

x = 180°/36

x = 5°

the first adjacent angle Be 11 x = 11 × 5 = 55°

the second adjacent angle be 25x = 25 × 5 = 125°

hence, the the angles are are 55° and 125° respectively
