Answer:

60°, arms 6

Step-by-step explanation:

let the total arms = n

total generated angles in a regular polygon is = (n-2)×180

now,

(n-2)×180 = 120 n

or, 180n - 360 =120n

or, 60n = 360

or, n = 6

If RS =14 and ST=9 , find RT. Use the number line below<br><br> RT=

Bingel [31]

Answer:

23

Step-by-step explanation:

RS = 14

ST = 9

That means S is in the middle of R and T because it has two line segments associated with it

RT = RS + ST

RT = 14 + 9

RT = 23

3x +15 = 2x + 10 + x + 5

Shkiper50 [21]

Answer:

The equation is true.

Step-by-step explanation:

Simplify. Combine like terms:

3x + 15 = (2x + x) + (10 + 5)

3x + 15 = (3x) + 15

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3x and 15 from both sides:

3x (-3x) + 15 (-15) = 3x (-3x) + 15 (-15)

3x - 3x = 15 - 15

0 = 0

~ True. The two expressions are equal to each other.

Write a linear function F with the values F(-9)=8 and F (0) =1

Fiesta28 [93]

Given:

The values of a linear function are $F(-9)=8$ and $F(0)=1$ .

To find:

The linear function.

Solution:

If a linear function passes through two points, then the equation of the linear function is:

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

The values of a linear function are $F(-9)=8$ and $F(0)=1$ . It means the function passes through the points (-9,8) and (0,1). So, the equation of the linear function is:

$y-8=\dfrac{1-8}{0-(-9)}(x-(-9))$

$y-8=\dfrac{-7}{9}(x+9)$

$y-8=\dfrac{-7}{9}(x)+\dfrac{-7}{9}(9)$

$y-8=\dfrac{-7}{9}x-7$

Adding 8 on both sides, we get

$y-8+8=\dfrac{-7}{9}x-7+8$

$y=\dfrac{-7}{9}x+1$

Putting $y=F(x)$ , we get

$F(x)=\dfrac{-7}{9}x+1$

Therefore, the required linear function is $F(x)=\dfrac{-7}{9}x+1$ .
