For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?
jekas [21]

The sum of the interior angles in the polygon whose side is 10 is 1440^{0}

<h3>What is sum of interior angle of polygon ?</h3>

The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon.

As, The formula for calculating the sum of interior angles is ( n − 2 ) × 180^{0}

S0, n=10

Then, sum of interior angle be = (n-2) x 180

                                                   = (10-2) x 180

                                                   = 8 x 180

                                                   = 1440^{0}

Thus, the sum of the interior angles in the polygon is 1440^{0}

you have 120 pieces of fabric to make a blanket. each piece of fabric is a square with a side length of 6 inches. you use as man
guapka [62]
To make a square blanket, you need to calculate the squareroot of 120, which is 10,954... so the biggest number is 10x10 peaces of fabric you can use to create a square blanket. These are 100 (so 20 are left over). To create a bigger square blanket of 11×11 peaces (11^2 = 121) you need one more peace of fabric. One peace is six inches, the blanket is 10 peaces long (6×10=60) The size would be 60inchesx60inches= 3.600 inches.

How do I do this? 50 points, please answer
xz_007 [3.2K]

Check the picture below.

now, the midsegment of a triangle, besides being half the base, we have to bear in mind that is a "mid" segment, is a segment that lies half-way along the segments it touches.

so for the triangle above, well, the midsegment DE is cutting the segment BC it two equal halves, BE and EC, that means that \stackrel{x}{BE}~~ = ~~\stackrel{8}{EC}.

The product of two consecutive positive integers is 18 more than eight times the smaller number. Find the two numbers.
olga2289 [7]

Let , smallest integer is x.

So , other one is x + 1.

By , given conditions :

x( x + 1 ) = 8x + 18\\\\x^2+x=8x+18\\\\x^2-7x-18=0\\\\x^2-9x+2x-18=0\\\\x(x-9)+2(x-9)=0\\\\x=-2 \  ,\ x = 9

Since, the numbers are positive so, x = -2 is ignored.

Therefore, the numbers are 9 and 10.

Hence, this is the required solution.

Show that y2+ x-3 =0 is an implicit solution to dy/dx =-1/ (2y) on the interval (- [infinity] , 3)
Sedaia [141]

Answer:

Implicit function

\frac{d y}{d x} = \frac{-1}{2y}

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given  y² + x - 3=0 ...(i)

Differentiating equation (i) with respective to 'x', we get

                   2 y \frac{d y}{d x} +1 = 0

           ⇒     2 y \frac{d y}{d x} = -1

           ⇒     \frac{d y}{d x} = \frac{-1}{2y}

                 \frac{d y}{d x} = \frac{-1}{2 (3)}

                 \frac{d y}{d x} = \frac{-1}{6}
