Question

twoangle of aparallelogram are in the rotio of 2:7 find all the angles

Answer 1

let

the angles are adjacent and be are 2x and 7x

In parallelogram

sum of adjacent angles is 180

so,

2x + 7x = 180

x = 20

so angles are 2× 20 =40

and 7× 20 = 140

Now ,

opposite angles of parallelogram are equal

so there arr two angles of 40

and two are of 140
