Question

In a parallelogram, if two adjacent angles are 4x° and 5x° then value of x
is​

Answer 1

Answer:

as we know adjacent angle of parallelogram is supplementary so

4x+5x=180

9x=180

x=180/9

x=20

so 1st angle =4x=4×20=80degree

2nd angle=5x=5×20=100degree

hope it may help you plz mark as brainlist

Answer 2

Answer:

X=20°
