Question

In quadrilateral three angle are in ratio 3:3:1 and one of the angles is 80° , then other angles are.....​

Answer 1

Answer:

120,120,40,80

Step-by-step explanation:

Angle Which are in ratio let them be x

And left one is 80°

So

Sum of a quadrilateral = 360

3x+3x+1x+80°=360

7x =280

X=280/7

X=40

So angle are 3x=3*40=120°

Second =3x= 3*40=120°

Third= 1*40=40°

Fourth (given) =80°

Answer 2

let three angles be x

Sum of all angles of quadrilateral = 360

3x+3x+x+80=360

7x=360-80

x=280/7

x= 40

now

3×40=120

3×40=120

1×40=40

So the three angles are 120,120,40
