Answer:
The length of apothem of given hexagon is 8.66 cm
Step-by-step explanation:
Apothem of a polygon is given by:

Here
s is length of side
tan is trigonometric function
and n denotes number of sides
Given that the polygon is a hexagon

Putting the values in the formula

Hence,
The length of apothem of given hexagon is 8.66 cm
A. is the answer.
the 2 triangls have AD = AC
and AB as a common side. therefore the triangls are congruent.
This is one example of a trinomial with a leading coefficient of 3 and a constant term of -5
