*trigonometry and area*
find the area of a regular hexagon with a side length of 8 cm. round to the nearest tenth.

The correct answer is that the area of the regular octagon is 309 cm²

Step-by-step explanation:

There are several formulas for calculating the area of a regular octagon. We will use this one for solving this question because it does not require additional information .

Area = (2 * s²)/tan 22,5°

s = 8 cm

Replacing with the real values, we have:

Area = (2 * 8²)/tan 22,5°

Area = 2 * 64/0.4142

Area = 128/0.4142

Area = 309 cm² (Rounding to the nearest tenth)

166.3 cm^2 to nearest tenth.

Explanation:

A hexagon is made up of 6 equilateral triangles.

Area of 1 triangle = 1/2 * 8 * height.

Using trig to find the height:

tan 60 = h / 4

h = 4 tan 60  = 6.928 cm

So the area of a triangle = 1/2 * 8 * 6.928

and area of the hexagon = 6 * 1/2  * 8 * 6.928

= 166.28 cm^2.

answer: all of the above

identity theft, is stealing other person's identity to commit fraud or other crimes. identities, are stolen through hi tech and low tech methods and all these can result in the consequences mentioned above. because a criminal when has stolen your identity, can get a loan under your name which will increase a debt burden on the victim, it will also make it harder for the victim to get a loan in the future due to poor credit history and as a result may face loss of a job. there will be a loss of money since the criminal can even rent or buy an apartment under your name.
