To find the angles inside of a regular polygon you use the sum (180(n-2))/n:
n being the number of sides.

You can then the eight sides into the equation to get:
(180(n-2))/n = (180(8-2)/8) = 135°

Each angle inside of the octagon is 135°

Hope this helps! :)

the answer is 135 degrees because google declares it as such. to argue with google is to argue with god. one does not argue with the savior of grades. the messiah of school. the benevolent ruler of our every question.

Answer:

C. 2.

Step-by-step explanation:

The graph descends from the left  so the coefficient of the leading term is negative. It is also a cubic equation with zeros of -20, about 6.5 and about 13. so we can write the equation as below.  The last 2 values can only be guessed because the x axis only shows values which are multiples of 5.

f(x) = a(x + 20)(x - 6.5)(x - 13)   where a is  a negative constant.

(This is only an approximation).

By the Remainder theorem, when the expression is divided by (x + 10):

f(-10) = -20 so we have

-20 = a (-10 + 20)(-10-6.5)(-10 - 13)

(10)(-16.5)(-23)a = -20

a = -20 / (10)(-16.5)(-23)

a = -0.0053

When  the equation is divided by (x - 10) then f(10)  is the remainder so substituting we have as the remainder:

-0.0053(10+20)(10-6.5)(10 -13)

-0.0053 * 30 * 3.5 * -3

= 1.7 approximately.

Looks like the answer is 2.

Rearrange each of the following formula so the pronumeral in the bracket becomes the subject of the equation
MakcuM [25]

Answer:

y = 9 - 3x

Step-by-step explanation:

9x + 3y - 27 = 0 ( add 27 to both sides )

9x + 3y = 27 ( subtract 9x from both sides )

3y = 27 - 9x ( divide through by 3 )

y = 9 - 3x

When fritz drives to work his trip takes 40 ​minutes, but when he takes the train it takes 30 minutes. find the distance fritz t
sweet-ann [11.9K]
Distance = rate*time

convert minutes to hour first because the question talking about 15 mile per hour
40 mins = 40/60 2/3 hrs
30 mins = 30/60 = 1/2hrs

Assume that s be the speed when Fritz driving, so
s + 15 will be the speed of the train.

We know the time we know the speed, Next
distance that Fritz drive = \frac{2}{3}s
distance the train travel = \frac{1}{2}(s+15)

The question: Assume that the train travels the same distance as the car
==> \frac{2}{3}s = \frac{1}{2}(s+15)
==> \frac{2}{3}s = \frac{1}{2}s + \frac{15}{2}
==> \frac{2}{3}s - \frac{1}{2}s = \frac{15}{2}
==> \frac{1}{6}s = \frac{15}{2}
==> \frac{6}{1} * \frac{1}{6}s = \frac{15}{2} * \frac{6}{1}
==> s = 45 
Now we know that Fritz drive at 45 mph, 
distance = \frac{2}{3} * 45 = 30 miles
