Use the graph below to answer the following question:
PolarNik [594]
X = -4 -> y = 4

x = 1 -> y = -1

So, rate = (4-(-1)) / (-4-1) = -1

Find the area of each shaded region each outer polygon is regular <br><br><br> See the picture
PSYCHO15rus [73]

Answer:

Area of the shaded region = 3.46 square units

Step-by-step explanation:

Measure of the interior angle of a regular polygon = \frac{(n - 2)\times180}{n}

From the picture attached,

Number of sides of the given polygon 'n' = 6

Interior angle (∠BAF) of the given polygon = \frac{(6 - 2)\times 180}{6}

                                                                       = 120°

Measure of ∠BAC = \frac{120}{4}

                              = 30°

Now we apply sine rule in ΔAGB,

sin(30°) = \frac{\text{Opposite side}}{\text{Hypotenuse}}

            = \frac{BG}{AB}

BG = AB[sin(30°)]

     = 2\times \frac{1}{2}

     = 1

By applying cosine rule in ΔABG,

cos(30°) = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

              = \frac{AG}{AB}

AG = AB[cos(30°)]

     = 2\times \frac{\sqrt{3} }{2}

     = \sqrt{3}

AC = 2(AG)

     = 2√3

Area of ΔABC = \frac{1}{2}(\text{Base})(\text{Height})

                       = \frac{1}{2}(AC)(BG)

                       = \frac{1}{2}(2\sqrt{3} )(1)

                       = \sqrt{3}

Area of the shaded region = Area of ΔABC + Area of ΔFED

                                             = 2(Area of ΔABC)

                                             = 2√3

                                             = 3.46 square units

6-2x=6x-10x+20  solve for x

combine like terms and get all to the same side of equation
6-2x+10x-6x=20
10x-2x-6x+6=20
8x=20-6
8x=14
x=14/8=7/4

What is the sum of the measure of the angles of a 25-gon
den301095 [7]
Since all the angles<span> congruent, to find the </span>measure<span> of just one </span>angle<span>, divide the </span>sum<span> of all the </span>angles<span> by the number of </span>angles<span>. thats how you find the anwser
