Question

the measure of two adjacent angles of a parllellogram are in ratio 5:4 .find the measure of each of the following​

Answer 1

Answer:

adjacent angles are equal to 180....

Step-by-step explanation:

let ratio= 5x and 4x

add both...

5x +4x =180

9x = 180

x= 180/9

x=20

5x= 100

4x=80

Answer 2

let x be the common variable

5x+4x=180°.....adj adjacent angles of parallelogram are supplimemtry

9x=180°

x=180/9

x=20°

first angle of the parallelogram is 5x

5x=5x20

=100°

second angle of the parallelogram is 4x

4x=4x20

=80°
