Question

What is the value of x? pleeaseee answer!!!

Answer 1

If you look up "angles of 7 sided polygon" it would give a result of how many degrees polygons with 7 sides such as this one above would equal to. It's important to know that when finding x angles within.

7-sided polygons = 900 degrees in total

Since all the other angles except x are given, we can add all those up and set it equal to 900. So it would look like this:

`139+121+125+126+158+120+x=900`

Simply solve for x now.

`139+121+125+126+158+120+x=900\\ \\ 789+x=900\\ \\ x=900-789=111`

So x = 111 degrees.

Hope this helps!
