In the regular nonagon shown, what is the measure of angle x? a 36° b 40° c 45° d 60°

180-140=40

b is the answer

Option B.

Step-by-step explanation:

A nonagon has 9 vertices. So, the number of exterior angles is 9.

We know that sum of exterior angles of any polygon is 360 degrees. So,

Sum of exterior angles of a nonagon = 360 degrees

The measures of all exterior angles of regular nonagon are same.

We need to find the measure of an exterior angle.

The measure of an exterior angle of a regular polygon is

Therefore, the correct option is b.

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
