Question

please tell me the answer​

Answer 1

Answer:

x = 40

Step-by-step explanation:

x + 2x-10 + x - 10 + 2x -10 +x - 10 + 2x - 40 = 360 ( sum of all angles of hexagon)

9x -0 = 360

9x = 360

x = 360/9

x = 40

Answer 2

Answer:

x = 80 degrees

Step-by-step explanation:

For any closed polygon having n number of sides, the sum of all its interior angle is given by

(n-2)*180

So for a hexagon no of side (n) = 6

So sum of all its interior angle will be (6-2)*180 = 4*180 = 720 degrees

Now the given angles must sum up to 720 degrees so

x + (2x-10) + (x-10) + (2x-10) + (x-10) + (2x+40) = 720

=> x + 2x + x+ 2x + x + 2x - 10 - 10 - 10 - 10 + 40 = 720

=> 9x + 40 -40 = 720

=> 9x = 720

=> x = 80
