The area of regular polygon with 5 sides is 689.65m²
<u>Explanation:</u>
All sides of a regular polygon are equal in length. If you know the length of one of the sides, the area is given by the formula:
![area = \frac{s^2n}{4 tan(\frac{180}{n}) }](https://tex.z-dn.net/?f=area%20%3D%20%5Cfrac%7Bs%5E2n%7D%7B4%20tan%28%5Cfrac%7B180%7D%7Bn%7D%29%20%7D)
where
s is the length of any side
n is the number of sides
tan is the tangent function calculated in degrees
Let the number of side of a polygon be 5. So, putting the values in equation
![area = \frac{(20)^2X5}{4 tan(\frac{180}{5}) } \\\\ = \frac{2000}{2.9} \\\\= 689.65 m^2](https://tex.z-dn.net/?f=area%20%3D%20%5Cfrac%7B%2820%29%5E2X5%7D%7B4%20tan%28%5Cfrac%7B180%7D%7B5%7D%29%20%7D%20%5C%5C%5C%5C%20%3D%20%5Cfrac%7B2000%7D%7B2.9%7D%20%5C%5C%5C%5C%3D%20689.65%20m%5E2)
Therefore, the area of regular polygon with 5 sides is 689.65m²
0≤h(t)≤144, which means that the height of the object can be between 0 and 144 feet, including those limits.
Answer:
Heart sounds
Step-by-step explanation:
- Your doctor has allergic reaction, febrile rash, and meningitis in their differential for the patient.
- In a healthy adult, the heart makes two sounds, commonly described as 'lub' and 'dub. ' The third and fourth sounds may be heard in some healthy people, but can indicate impairment of the heart function. S1 and S2 are high-pitched and S3 and S4 are low-pitched sounds.
