The convex polygon below has 8 sides. Find the value of x ?

bulgar [2K]

The missing interior angle, x, of the convex polygon is 168⁰.

<h3>Sum of interior angles of convex polygon</h3>

The sum of interior angles of a convex polygon is calculated as follows;

S = (n - 2) 180

S = (8 - 2) 180

S = (6) 180

S = 1080

The missing interior angle, x, is calculated as follows;

x + 126 + 146 + 130 + 140 + 146 + 134 + 90 = 1080

x + 912 = 1080

x = 1080 - 912

x = 168⁰

D - -x^2 + 3x + 7

To find this, first write out the equation:

(3x + 1) - (x^2 - 6)

Distribute the negative into x^2 and -6 so you're equation now looks like this:

3 x + 1 - x^2 + 6

Combine like terms and arrange the equation into ax^2 + bx + c to get the final answer of:

-x^2 + 3x + 7

Hope this helps!

Donatello starts with a marble cube of side length $10.$ He then slices a pyramid off each corner, so that in the resulting poly

prohojiy [21]

Answer:

The length of each side of the polyhedron, s is 4.142 or

= $10(\sqrt{2}-1)$

Step-by-step explanation:

If we take the distance of the length of the side of the cube where Donatello make the cut to the corner of the cube as x we get the side of length each polyhedron as

$\sqrt{x^2 + x^2} = \sqrt{2x^2} =x\sqrt{2}$

x·√2 because we have an hy

Therefore, the original cube had sides of length

10 = 2·x + x·√2

Solving for x we get

$x = \frac{10}{\sqrt{2}+2 }$

Therefore the length of s is x·√2 which gives

$s = x\sqrt{2} = \frac{10}{\sqrt{2}+2 }\sqrt{2} = 10\sqrt{2} -10 = 10(\sqrt{2}-1) = 4.142$

The length of each side of the polyhedron, s = 4.142.

Bryce buys a treadmill online for $510. If shipping and handling are an additional 21 <img src="https://tex.z-dn.net/?f=%5Cfrac%

scZoUnD [109]

Answer:

The shipping and handling charge that Bryce paid is $109.65

Step-by-step explanation:

Given as :

The online price of the treadmill = $510

The charge of shipping and handling = 21 $\dfrac{1}{2}$ % of online price

Let The shipping and handling charge that Bryce paid = $x

<u>Now, According to question</u>

∵ The charge of shipping and handling = 21 $\dfrac{1}{2}$ % of online price

So, x = $\dfrac{43}{2}$ % of $510

Or, x = $\dfrac{43\times 510}{100\times 2}$

Or, x = $109.65

The shipping and handling charge that Bryce paid = x = $109.65

Hence,The shipping and handling charge that Bryce paid is $109.65 Answer
