Answer:
• changing an interior angle to a reflex angle
Step-by-step explanation:
In order for the outline of the polygon to have a pair of sides that is concave (pointed inward, rather than outward), the corresponding interior angle must be a reflex angle. (It must measure more than 180°.) Draw one; you'll see.

Step-by-step explanation:
The roots of the equation is x = 4.56 OR x = 0.44
<h3>Quadratic equation</h3>
From the question, we are to determine the roots of the given equation
The given equation is
x² -5x +2 = 0
Using the formula method,
![x =\frac{-b \pm \sqrt{b^{2}-4ac } }{2a}](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B-b%20%5Cpm%20%5Csqrt%7Bb%5E%7B2%7D-4ac%20%7D%20%7D%7B2a%7D)
In the given equation,
a = 1, b = -5, c = 2
Putting the values into the formula,
![x =\frac{-(-5) \pm \sqrt{(-5)^{2}-4(1)(2) } }{2(1)}](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B-%28-5%29%20%5Cpm%20%5Csqrt%7B%28-5%29%5E%7B2%7D-4%281%29%282%29%20%7D%20%7D%7B2%281%29%7D)
![x =\frac{5 \pm \sqrt{25-8} }{2}](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B5%20%5Cpm%20%5Csqrt%7B25-8%7D%20%7D%7B2%7D)
![x =\frac{5 \pm \sqrt{17} }{2}](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B5%20%5Cpm%20%5Csqrt%7B17%7D%20%7D%7B2%7D)
OR ![x =\frac{5 - \sqrt{17} }{2}](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B5%20-%20%5Csqrt%7B17%7D%20%7D%7B2%7D)
OR ![x =\frac{5 - 4.12}{2}](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B5%20-%204.12%7D%7B2%7D)
OR ![x =\frac{0.88}{2}](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B0.88%7D%7B2%7D)
x = 4.56 OR x = 0.44
Hence, the roots of the equation is x = 4.56 OR x = 0.44

Answer:
56.4
Step-by-step explanation:
To convert decimal number 86.25, we convert its integer and fraction part individually and then add them to get the equivalent hexadecimal number, as below:
To convert integer 86 to hexadecimal, follow these steps:
Divide 86 by 16 keeping notice of the quotient and the remainder. Continue dividing the quotient by 2 until you get a quotient of zero.
Then just write out the remainders in the reverse order to get the equivalent hexadecimal number.
86 / 16 = 5 with remainder 6
5 / 16 = 0 with remainder 5
Here is the answer to 86 decimal to hexadecimal number:
56
For converting decimal fraction 0.25 to hexadecimal number, follow these steps:
Multiply 0.25 by 16 keeping notice of the resulting integer and fractional part. Continue multiplying by 16 until you get a resulting fractional part equal to zero (we calcuclate upto ten digits).
Then just write out the integer parts from the results of each multiplication to get equivalent hexadecimal number.
0.25 × 16 = 4 + 0
Here is the answer to 0.25 decimal to hexadecimal number:
0.4
Therefore, decimal number 86.25 converted to hexadecimal is equal: 56.4
