What is the measure of an angle of a regular polygon with nine sides?

Elden [556K]

Answer:

140 degrees

Step-by-step explanation:

To find the value of an internal angle within this polygon, we can just multiply the number of triangles by 180 ° , then divide by the number of internal angles, which is nine. Excellent! So the interior angle of a 9 -sided polygon is 140 ° .

Natasha, Peter and Malachy share ?56 in a ratio 1:1:2. How much money does each person get? Natasha: ?? Peter: ?? Malachy: ??

Ahat [919]

Answer:

Natasha = 1 x 14 = 14

Peter = 2 x 14 = 28

Malachy = 1 x 14 = 14

Step-by-step explanation:

Ratio 1:1:2 so 1 + 1 + 2 = 4

Natasha, Peter and Malachy share of 56 : 56/4 = 14

Natasha = 1 x 14 = 14

Peter = 2 x 14 = 28

Malachy = 1 x 14 = 14

Drag the tiles to the boxes to form correct pairs. Not all tiles will be used. Match the resulting values to the corresponding l

belka [17]

The correct solution to the limits of x in the tiles can be seen below.

$\mathbf{ \lim_{x \to 9^+} (\dfrac{|x-9|}{-x^2-34+387}) }$ $\mathbf{ = -\dfrac{1}{52} }$

$\mathbf{ \lim_{x \to 8^-} (\dfrac{8-x}{|-x^2-63x+568|}) }$ $\mathbf{=\dfrac{1}{79} }$

$\mathbf{ \lim_{x \to 7^+} (\dfrac{|-x^2-17x+168| }{x-7}) }$ = -31

$\mathbf{ \lim_{x \to 6^-} (\dfrac{|x-6| }{-x^2-86x+552}) }$ $\mathbf{ =\dfrac{1}{98}}$

<h3>What are the corresponding limits of x?</h3>

The limits of x approaching a given number of a quadratic equation can be determined by knowing the value of x at that given number and substituting the value of x into the quadratic equation.

From the given diagram, we have:

$\mathbf{ \lim_{x \to 9^+} (\dfrac{|x-9|}{-x^2-34+387}) }$

So, x - 9 is positive when x → 9⁺. Therefore, |x -9) = x - 9

$\mathbf{ \lim_{x \to 9^+} (\dfrac{x-9}{-x^2-34+387}) }$
