Question

If the angle measures of the interior angles of a pentagon are 130 degrees, 94 degrees, 109 degrees, 112 degrees, and X degrees. Find X?!

Answer 1

My question is from the polygon angle sum therom btw.

Answer 2

Yes, it is.

The sum of the interior angle measures is (n-2)*180. n = 5 for the 5 sides of a pentagon.

So, first up, what is the sum of the interior angle measures of a pentagon?

Answer 3

To get x, we need that sum.

130 + 94 + 109 + 112 + x = ? --> the sum goes here.

Answer 4

(n-2)*180. n = 5

(5-2)*180 = ? @XtraStupid

Answer 5

These are the only answers though. X= 95, x=105, x=108, or x=275 ??

Answer 6

I still dont know what the answer is :(

Answer 7

If you would work with me and not look at the answers, that would be great.

We cannot solve this problem until you find the sum of the angles measures of a pentagon.

So, for the third time, I am asking you to perform this calculation

(5-2)*180 = ?

In short, what is three times 180 equal to? Please post the answer.

We need it for the equation. We are nowhere near the answer so don't look at the options.

Answer 8

What is three times 180 equal to? Please post the answer.

Answer 9

Oh my bad. It's 540

Answer 10

Okay.

130 + 94 + 109 + 112 + x = 540

^^ Solve that equation for x.

Post what you get so we can compare answers, okay?

Answer 11

x would equal 95 :D omgeeee i think i did it lol!!!

Answer 12

95 is what I got, too.

Answer 13

100 percent. you helped so much thank you (:

Answer 14

You are welcome.
