Question

Two adjacent angles of a parallelogram are in ratio 4:5. find the measure of all rights.

Answer 1

Answer:

80, 100 degrees

Step-by-step explanation:

Sum of adjacent angles = 180

Let the angles be 4x and 5x

So 4x + 5x = 180

9x = 180

x = 20

So angles = 4x, 5x = 80, 100

Hope it helps

Answer 2

Answer:

Step-by-step explanation:

Let the angles be 4x:5x

4x+5x=180 (linear pair)

9x=180

x=180/9

x=20

=>4x= 20*4=80

5x=20*5=100
