Answer:

It is 92.

Step-by-step explanation:

If 140 degrees is the exterior, then we can find the interior by doing 180-140. We get 40, so that means the "c" interior angle is 40 degrees. Since 3 angles added together is 180 degrees, we can make this equation: (2x)+(x+2)+40=180. The "x+2" and "2x" don't need to be in parenthesis but I wrote it like that so it wouldn't confuse you. Once you solve that, the answer should be x=46. Then multiply by 2 and get 92.

Answer:

92

Step-by-step explanation:

You can use the exterior angle theorem:

3x + 2 + 40 = 180

3x = 138

x = 46

2 * 46 = 92

If g(x) = -3x + 12, what is the solution set<br> if the domain of gis (-2, 0,2}?
disa [49]

Given:

The function is

g(x)=-3x+12

Consider the given domain of g is {-2,0,2}.

To find:

The solution set  if the domain of g for the given domain.

Solution:

Domain is the set of input values and range is the set of output value.

We have,

g(x)=-3x+12

Domain of g is {-2,0,2}.

For x=-2,

g(-2)=-3(-2)+12

g(-2)=6+12

g(-2)=18

For x=0,

g(0)=-3(0)+12

g(0)=0+12

g(0)=12

For x=2,

g(2)=-3(2)+12

g(2)=-6+12

g(2)=6

Now, the solution set  of the given domain of g is

\{f(-2),f(0),f(2)\}=\{18,12,6\}

Therefore, the solution set is {18,12,6}.
