The four angles of a quadrilateral are in the ratio 3:4:6:7. Find the angles.​

Answer 1

Step-by-step explanation:

angles of a quadrilateral 3:4:4:7

sum of angles in a quadrilateral =360

∘

let the angles be 3x,4x,4x and 7x.

then, sum 360

3x+4x+4x+7x=360

18x=360

x=20

3x=60,4x=80,7x=140

∴ the angle of quadrilateral are 60,80 and 140.

Answer 2

Answer:

angles of a quadrilateral 3:4:4:7

sum of angles in a quadrilateral =360 °

let the angles be 3x,4x,4x and 7x.

then, sum 360

3x+4x+4x+7x=360

18x=360

x=20

3x=60,4x=80,7x=140

 the angle of quadrilateral are 60,80 and 140.
