Answer:
see explanation
Step-by-step explanation:
If f(x) and g(x) are the inverses of each other, then
f(g(x)) = g(f(x)) = x
f(g(x)) = f(x - 
) = x - + = x
g(f(x)) = g(x + ) = x + - = x
Hence f(x) and g(x) are the inverse of each other

Answer:
60 cm²
Step-by-step explanation:
base = 10
Height = √13² - 5² = √144 = 12
area = 1/2BH = 1/2 * 10 * 12 = 60
Getting the central area of a polygon is not possible. Probably the question refers to the central angle. In a a regular polygon, getting the central angle is that you need to use the formula.
Central Angle of a polygon = 360 degrees / number of sides of a polygon.
Why 360 degrees? Because, a circle has a total of 360 degrees. And a circle is a polygon with no sides.
