Answer:

Step-by-step explanation:
we have



we know that
The variable of the function f(g(x)) is equal to the function g(x)
so
f(x) -----> f(g(x))
x^{8} -----> (x+5)^{8}
The variable x becomes (x+5)
therefore
The function g(x) is equal to

Sum of Interior Angles
The interior angles of any polygon always add up to a constant value, which depends only on the number of sides. For example the interior angles of a pentagon always add up to 540° no matter if it regular or irregular, convex or concave, or what size and shape it is. The sum of the interior angles of a polygon is given by the formula:
sum = 180 ( n − 2 )
