please..mark..it..as..brainlist.if..you..got..the..right..answer

Step-by-step explanation:

∠A:∠B:∠C:∠D=1:2:3:4

So, let ∠A=x,∠B=2x,∠C=3x,∠D=4x

Therefore, by angle sum property of quadrilateral,

x+2x+3x+4x=360

10x=360

x=36  

Hence,

∠A=36  

,∠B=72  

,∠C=108  

,∠D=144  

Answer 2

Answer:

let's the measure of angle be x

1x+2x+4x+5x

= 360 degree

12x= 360 degree

x=360/12

x=30 degree
