Answer 1

✨✨✨ANSWER

NOW .....

$720° - (x + 10° + 2x + 20° + 2x - 20° + 3x - 50° + x + 40° + x + 20°) = 0 \\ 720° - 10x - 20° = 0 \\ x = 70°$

Answer 2

Answer:

the answer is x=70

Step-by-step explanation:

the sum of all interior angles of a polygon = 180*(n-2) where n is no. of sides

here in this case we have a hexagon

so there are 6 sides in a hexagon

when we apply this formula we get

sum of all interior angles of a hexagon = 180*(6-2)

                                                                =180*4

                                                                =720

now according to the question

all angle is-

x+10,2x+20,2x-20,3x-50,x+40,x+20.

x+10+2x+20+2x-20+3x-50+x+40+x+20=720

3x+30+5x-70+2x+60=720

10x+20=720

10x=700

x=700/10

x=70

the value of x is 70
