Question

the measures of two adjacent angles of a parallelogram are in the ratio 5: 4 find the measure of each of the angles of a parallelogram​

Answer 1

Step-by-step explanation:

two adjacent angles of a parallelogram are in the ratio 5:4

let one angle be 5x

and other angle be 4x

as we know that sum of adjacent sides of parallelogram =180

5x+4x=180

9x=180

x=180/9

x=20

the measure of angles are:5(20)=100

and measure of other angle :4(20)=80
