I would like to know the process for dis ive been struggling on them. i tried to ask the teacher but they made it more confusing
Dafna11 [192]

Answer:

31.177 m

Step-by-step explanation:

So the formula of a hexagon is  Area = (3√3 s^2)/ 2

s = side in this problem.  A hexagon is made up of 6 equilateral triangles, so the distance from the center is equal to each of the sides.

For this problem, plug and chug.  Plug your knowns into equation and you will find the answer.

s^2 = (2√3)^2 = 12

Area = (3√3 x 12)/2 = 31.1769 m

I am not sure how many decimals you are supposed to round, probably 3 so in that case 31.177 m

Please help!! dont answer if you're not going to explain! need help with my geometry!
FinnZ [79.3K]

Step-by-step explanation:

Statement:

2-) ∠BAC = ∠EDC

<em>Reason:</em>

Angles opposite to equal sides of a triangle are equal (Alternate Interior Angles Theorem)

Statement:

3-) AC = CD

<em>Reason:</em>

CPCTC ("Corresponding Parts of Congruent Triangles are Congruent")

Statement:

4-) ∠BCA = ∠DCE

<em>Reason:</em>

Vertical Angles Theorem (states that vertical angles, angles that are opposite each other and formed by two intersecting straight lines, are congruent)

Statement:

5-) triangle ABC = triangle DEC

ASA Postulate

The ASA (Angle-Side-Angle) postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent. (The included side is the side between the vertices of the two angles.)
