Answer:
let angle be x
1x+2x+2x+4x=360° (sum of angle of quadrilateral is 360°)
9x=360°
360/9=x
40=x
Therefore angles of quadrilateral are 1×40=40°
2×40=80°
2×40=80°
4×40=160°

Answer:
40°,80°,80°and 160°.
Step-by-step explanation:
Let the first quadrilateral angle is x
second quadrilateral angle is 2x
Third quadrilateral angle is 2x
fourth quadrilateral angle is 4x
x+2x+2x+4x=360°
9x=360°
x=40 °
First quadrilateral angle is x=40°
second quadrilateral angle is 2x=2×40=80°
Third quadrilateral angle is 2x=2×40=80°
Fourth quadrilateral angle is 4x=4×40=160°
Answer 40°,80°,80°,160°
