Answer 2

Answer:

✯Given:

The measure of two ajacent angles of a parallelogram are in ratio 4:5.

✯To find:

measure of each angle of a parallelogram

✯Solution:

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
