Question

the adjacent angles of a parallelogram are in the ratio4:5 then the smallest angle is ​

Answer 1

Step-by-step explanation:

Sum of the adjacent angles in any parallelogram= 180

ratio of adjacent angles = 4:5 (given)

let first angle = 4x

second angle = 5x

4x+5x=180

9x=180

x=180/9

x= 20

therefore

required angles are

first angle = 4x= 4*20 =80

second angle = 5x= 5*20 =100

Answer 2

Answer:

the smallest angle of the given parallelogram is 80°
