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:
Simply solve for x now.
So x = 111 degrees.
Hope this helps!
Answer is 20. -4 x 1 is -4 so it doesn’t change. -4 -8 makes it -4 + 8 as there’s two negatives. 9 divided by 3 is 3. So it’s -4 +8 x 3. 8x3 is 24. So -4 + 24 = 20. Therefore final answer is 20
The answer might be 226.2

Answer:
x = 10√3
Step-by-step explanation:
The Pythagorean theorem tells you ...
FB^2 = BC^2 +CF^2
FA^2 = FB^2 +BA^2
Substituting for FB^2, we have ...
FA^2 = BC^2 +CF^2 +BA^2 = x^2 +x^2 +x^2
FA^2 = 3x^2
FA = x√3 = 30 . . . . take the square root and substitute for FA
x = 30/√3
x = 10√3
