What is the sum of the measures of the exterior angles in a nonagon? explain

Mathematics
1 answer:
DedPeter [7]3 years ago
5 0

The sum of the measures of all exterior angle in a polygon with n sides is always 360^{\circ}.

Nonagon is a polygon with 9 sides. If this nonagon is regular or equiangular, then all interior angle are congruent, and therefore all exterior angles are congruent. Then the measure of each exterior angle is \dfrac{360^{\circ}}{9} =40^{\circ}.

Need help solving for relative frequency please!
Sunny_sXe [5.5K]

Answer:

Kindly check explanation

Step-by-step explanation:

Given :

Relative frequency = frequency / total frequency

Total frequency = 389+335+975+351+72 = 2122

Response ________ Frequency __ R/ frequency

Never ____________ 389 _ 389/2122 = 0.180

Rarely ____________ 335 _ 335/2122 = 0.158

Sometimes _________975 _975/2122 = 0.459

Most of the time _____ 351 _ 351/2122 = 0.165

Always ____________ 72 __ 72/2122 = 0.034

Find the value of the length <br> x<br> rounded to 1 DP.
bagirrra123 [75]

Length of x is 98.2 m

<u>Step-by-step explanation:</u>

Step 1:

Use the trigonometric ratio tan 27° to find the common side of both the right angled triangles.

tan 27° = opposite side/adjacent side = opposite side/9

∴ Opposite side = 9 tan 27° = 9 × - 3.27 = -29.46 m

Step 2:

Use this side and trigonometric ratio cosine to find the value of x.

cos 49° = adjacent side/x = -29.46/x

∴ x = -29.46/cos 49° = -29.46/0.30

     = 98.2 m (negative value neglected)

NEED HELP WITH PART B
Sergeu [11.5K]

Answer:

y = -20x + 100

Step-by-step explanation:

As per your requirement For Part B, the solution is

The equation in slope-intercept form to model the relations is below:-

To reach 2 points on the graph the line passes through

lets use p1(0, 100), p2(1, 80)

now we will compute the slope:

m = \frac{(y2 - y1)}{(x2 - x1)}

m = \frac{(80 - 100)}{(1 - 0)}

= -20

and now use line equation in form point-slope:

y - y1 = m(x - x1)

y - 100 = -20(x - 0)

y = -20x + 100

Question:
kykrilka [37]
What we know:
- number of meeting rooms = m
- chairs in each meeting room = 325

Since we need an equation to represent the number of chairs in m meeting rooms, we would multiply the amount of chairs per meeting room (325) by m. This amount is c. So the equation becomes:

c = 325m

Now the question asks for the amount of chairs if there are 7 meeting rooms in the hotel. To find this, substitute 7 for m into c = 325m.

c = 325m
c = 325(7)
c = 2275

Answer:
The equation is c = 325m, and the amount of chairs if m equals 7 is 2,275.
