Answer:
BC=20
AE= 18
<ABC= 114 degrees, <DAB=66 degrees
Step-by-step explanation:
To find DAB you subtract 180 from 114
To determine the slope, you can use the following formula:
(y2-y1)/(x2-x1)
Answer:
|AB| = √((7 - (-2))^2 + (-3 - 9)^2) = 15
|BC| = √((-2 - 7)^2 + (-3 - (-3))^2) = 9
|AC| = √((-2 - (-2))^2 + (-3 - 9)^2) = 12
Perimeter = 15 + 9 + 12 = 36
Answer:
Option (D)
Step-by-step explanation:
Formula to get the area of a regular polygon in a circle will be,
Area = ![n[\frac{1}{2}\times (\text{Base})\times (\text{Height})]](https://tex.z-dn.net/?f=n%5B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%28%5Ctext%7BBase%7D%29%5Ctimes%20%28%5Ctext%7BHeight%7D%29%5D)
= ![n[\frac{1}{2}\times (\text{s})\times (\text{h})]](https://tex.z-dn.net/?f=n%5B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%28%5Ctext%7Bs%7D%29%5Ctimes%20%28%5Ctext%7Bh%7D%29%5D)
Here 'n' is the number of sides.
If n increases, h approaches r so that 'rh' approaches r².
In other words, if the number of sides of the polygon gets increased, area of the polygon approaches the area of the circle.
Therefore, Option (4) will be the answer.
