The sum of the exterior angles of any polygon is 360 degrees. Therefore to find the measure of one exterior angle of any regular (all angles are congruent) polygon, divide 360 by the number of angles. In the case of a regular nonagon, the measure of one exterior angle is 40 degrees: 360 / 9 = 40 degrees. its my best guess

Answer:

9.2

Step-by-step explanation:

The given triangle is a right angled triangle. To solve for any of the side length of such triangle, apply the trigonometry ratio formula which can easily be remembered as SOHCAHTOA.

SOH is Sin θ = opposite/hypothenuse,

CAH is Cos θ = Adjacent/hypotenuse

TOA is Tan θ = Opposite/adjacent

Thus, in the right triangle given, we have:

θ = 38°

Opposite side to the given angle = x

Hypotenuse = 15

We're going to use, sin θ = opposite/hypotenuse

Sin(38) = x/15

Multiply both sides by 15 to solve for x

15*sin(38) = x

15*0.616 = x

9.24 = x

<em>x ≈ 9.2 (to nearest tenth)</em>

Which of the following is equal to 20x + 8y - 80?
Andrews [41]
It would be C because if you take out the four, the coefficients are multiples of 4 so it simplifies down.

In the school store, pencils cost 15 cents each and erasers cost 10 cents each. There is no tax. Gabby wants to spend exactly $2
kakasveta [241]

she bought 10 pencils and 5 erasers

Let x represent the number of pencils and y represent the number of erasers.

Gabby wants to spend exactly $2.00 on pencils and erasers, hence:

0.15x - 0.1y = 2        (1)

Therefore x = 10 and y = 5

Therefore she bought 10 pencils and 5 erasers.

Does anyone know how to do these? I'm having a hard time and you guys are very helpful.
n200080 [17]

Ok so keep in mind, we are solving for x or z. We want to get it by itself.

So, with 6x= 5x+22, we need to subtract 5x from both sides of the = sign

So 6x - 5x = 1x.

Our new equation looks like 1x= 22

We still don't have x alone so we need to divide one on both sides of the =

Our new and final answer is x=22
