Question

4) Two adjacent angles of a parallelogram
are in the ratio of 5:4 then their
measures are_and_​

Answer 1

Answer:

i hope this help you

Step-by-step explanation:

given ratio of two angles of parallelogram=4:5

we know that, 

sum of adjacent angles of parallelogram = 180 degree

let the common multiple between the given ratio be x

therefore be 4x and 5x

=>4x+5x=180

=>9x=180

=>x=20

therefore, 4x=80, 5x=100

as the opposite angles of quadrilateral are equal, the other angles are 80 and 100

hence the angles of the parallelogram are 80, 100, 80, 100
