Length of the apothem is 4.33 units.

Step-by-step explanation:

The regular hexagon can be divided into 6 equal equilateral triangle.

So ΔAED is an equilateral triangle.

In an equilateral triangle, the altitude bisects the angle, so

In ΔAHD,

answer: it is d

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
