Question

find the value of x
​

Answer 1

Answer:

hey dear here u go~

Step-by-step explanation:

apply angle sum property in a quadrilateral

therefore ,

3x+20 + 4x+5x+2x+18 = 360

14 x + 38 = 360

14 x = 322

x = 23

hope it helps

Answer 2

Answer:

here the diagram is quadrilateral

so we know that sum of interior angles of quadrilateral is 360 so,

[tex]2x + 18 + 3x + 20 + 4x + 5x = 360 \\ 14x + 38 = 360 \\ 14x = 322 \\ x =
