please answer asap​

Answer 1

Answer:

Let ∠A and ∠B are two adjacent angles.

But we know that sum of adjacent angles of a parallelogram is 180

∠A+∠B=180

Given that adjacent angles of a parallelogram are in the ratio 4:5 and let that ratio be multiple of x

∠A+∠B=180

4x+5x=180

9x=180

x=180/9

x=20

∠A=4x=4×20=80

∠B=5x=5×20=100
