Question

What is the value of x ?
​

Answer 1

Let us first consider how many sides this figure has:

⇒ it has 6 sides

Now to find the supposed sum of all the angles added up together for a hexagon, must use:

⇒
`Formula =(n-2)*180`

• n: # of sides

Let's plug in the number of sides:

`Sum_.of_.angles=(6-2)*180=720`

Therefore all the angles of a hexagon must equal 720 degrees:

`x + 90 + 110+160+90+140=720\\x + 590=720\\x = 130`

The value of x is 130.

Answer: 130

Hope that helps!
