Answer 2

Step-by-step explanation:

given:

Adjacent angles of a parallelogram are in the

ratio of 2:7 their values will be

to find :

their values will be

solution :

• let the ratio be x..

• 1st angle=2x

• 2nd angle=7x

• we know that sum of two adjacent angles of parallelogram =180

• 7x+2x=180 9x=180

• x=20

• SO...

• 1st angle=2x=2x20=40 2nd angle-7x= 7x20=140
