Which polygon has an interior angle sum of 1260°?

Liono4ka [1.6K]

Answer:

Step-by-step explanation:

Sum of interior angle of any polygon =(n-2) × 180°where n represents the number of sides in any polygon.

Or 1260 =(n-2)x180

Dividing both sides by 180:

7=n-2

Adding both sides by 2 we have :

n=9.

Hence a nanogon will have the sum of interior angles as 1260°.

Calculate the average (arithmetic mean) of the list of numbers shown in the table. (rounded to the nearest tenth) A) 35.2 B) 39.

jenyasd209 [6]

<h3><u>Given Numbers:-</u></h3>

23, 33 ,33 ,27 ,25 ,68 ,27 ,44 ,72

average of this set of numbers

<h3><u>Solution</u>:-</h3>

$\green{ \underline { \boxed{ \sf{Average = \frac{Sum \:of \: observation}{Number \:of \: observation}}}}}$

$\longrightarrow$ Here, no of observation are 9

Now,

$\begin{gathered}\implies \small \sf Average =\frac{23+33+33+27+25+68+27+44+72}{9}\\\end{gathered}$

$\begin{gathered}\\\implies \small \sf Average =\frac{56+60+93+71+72}{9}\\\end{gathered}$

$\begin{gathered}\\\implies \sf Average =\frac{116+164+72}{9}\\\end{gathered}$

$\begin{gathered}\\\implies \sf Average =\frac{352}{9}\\\end{gathered}$

$\begin{gathered}\\\implies \sf Average = 39.1 \\\end{gathered}$

$\longrightarrow$ The Average of given set of numbers is 39.1 .

∴ Option C) is correct ✔️
