Answer:
540°
Step-by-step explanation:
Formula: note that n means nr of sides
(n-2)×180°
(5-2)×180°=3×180=540°
Where each angle are 540°÷5=108°
For this case we have the following functions:

By definition we have to:

So:

By definition, the domain of a function is given by the values for which the function is defined.
The domain of m(x) is given by all reals except 1.
The domain of n(x) is given by all reals.
While the domain of
is given by:
All reals, except the 1. With
, the denominator is 0 and the function is no longer defined.
Answer:
Domain of
is given by all reals except 1.
Answer:

Step-by-step explanation:
One-fourth x + 2 = 

Next, we Expand the Left hand Side by multiplying each term in the bracket by 1/4

Bringing terms with x to the left Hand Side i.e. collecting like terms

On Cross multiplying
7x = -7 X 8

x=-8
Answer: 
Step-by-step explanation:
Domain: x-axis
Range: y-axis
The relation graph shows the points in which the domain is located. To find the Domain, go to the point in the x-axis (the horizontal line) and note the number where the point lies. For this question, the point on the left side of the graph lies on negative four (
), and on the right side, the point is on 6. Therefore, the domain of this relation is negative four is greater than/equal to x is less than/equal to six. It could also be written like this:

Answer:
x=92
Step-by-step explanation:
those to angles are supplementary meaning that they add up to equal 180
so you set up the equation 180=x+x-4
180=2x-4
step 1 add 4 to each side
184=2x
step 2 divide each side by 2
x=92
so the angles equal 92 and 88
