Question

If adjacent angle a and b of parallelogram abcd are in the ratio 7:5 then find all the angle of it

Answer 1

we know that adjacent angles of a parallelogram are supplementary.

7x +5x =180

12x =180

x =15

The angles are 105, 75 , 105 , 75

Answer 2

Hey!

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Adjacent angles of 11gm are supplementary

Let the ratio be x

7x+5x =180°

12x =180°

x= 180/12

x= 15

So angles are :-

7×15= 105

5×15= 75
