The polygon with 8 sides and a concave shape
Step-by-step explanation:
A polygon is any two-dimensional structure shaped by straight lines. Triangles, quadrilaterals, pentagons and hexagons are representations of polygons. You see, the name shows you how many sides the form has.
If in octagon all angles are equal and all sides are equal, it is considered a normal octagon, then it is classified as an unusual octagon. When the interior angle of the octagon is greater than 180 °, it is called the concave octagon.
Answer:
d) 4 ± 5i
Step-by-step explanation:
Here we have to use the quadratic formula.
x =
In the given equation x^2 - 8x + 41 = 0, a =1, b = -8 and c = 41
Now plug in the given values in the above formula, we get
x =
Simplifying the above, we get
x =
x =
[√-100 = √-1 *√100 = i*10 = 10i] because the value of √-1 = i]
x = (8 ± 10i )/2
Now dividing by 2, we get
x = 4 ± 5i
The answer is d) 4 ± 5i
Hope you will understand the concept.
Thank you.
