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!

kicyunya [14]

Answer:

The maximum area of a rectangle results from it being a square. The rectangle (or square) must have 4 equal sides in order to maximize area. But in this case, one side is a wall. That means that the remaining three sides will be = 60 / 3 = 20 feet long. You formed an square that is 20 ft x 20 ft = 400 ft²
