The length of one side of the octagon is given by:

Then, the apothem can be determined using the Pythagorean theorem in the following way:

Clearing to have:

Then, the area is given by:

Where,
L: length of the octagon sides
a: apotema
Substituting values:
Answer:
the approximate length of the apothem is:
a = 10.91 feet
The approximate area of the floor of the gazebo is:
A = 392.76 feet ^ 2
80,000,000 + 9,000,000 + 100,00 + 70,000 +300 + 20 + 6
Answer:
Step-by-step explanation:
The answer is A. 16+10+20= 46
X=116 degrees
The relationship between the two angles in the figure are congruent:)
The quadratic equation with roots a and b is given by:

Here a=1/2 and b=-4.
So the equation is given by:

The quadratic equation is as shown above.
