47, 57, 67, 77 are the numbers.
Answer:

Step-by-step explanation:
we know that
The measurement of the external angle is the semi-difference of the arcs which comprises
In this problem
m∠RPS=
------> external angle
so
m∠RPS=
we have
m∠RPS=

substitute the values

Solve for arc RS


Answer:
314 inches³
Step-by-step explanation:
The area of a cone is πr²h/3. We need to find the height and radius of the cone. The height is 12 inches. radius * 2 = diameter.
Radius * 2 = Diameter
/2 /2
Radius = 1/2* Diameter
Radius = 5 inches
We substitute it in:
3.14 * 5² * 12/3:
3.14*25*4
314 inches³
The number . . . . . N
The difference of the number and 9 . . . N-9
Seven times that difference . . . . . . . 7(N-9)
You said that 7(N-9) = 2 .
Divide each side by 7 : N - 9 = 2/7
Add 9 to each side: N = 9 and 2/7
