s angles

Answer 1

Step-by-step explanation:

i think this is correct answer

Answer 2

Answer:

x=18

2x=36

8x=144

9x=162

Step-by-step explanation:

let the angles of quadrilateral be x,2x,8x,9x

The sum of all the angles of a quadrilateral is 360°

x+2x+8x+9x=360°

20x=360°

x=360°/20

x=18

x=18

2x=2*18=36

8x=8*18=144

9x=9*18=162
