The angle of impact is 30°
<h3>What is the angle of impact?</h3>
In a bloodstain, the angle of impact can be used to determine the appearance of the resulting bloodstain if the bloodstain has a tail or pattern.
- Bloodstain pattern analysis is the study of bloodstains at a scene of the crime in an attempt to reconstruct the events that resulted in the bloodshed.
Mathematically;
![\mathbf{Angle \ of \ impact = sin^{-1} (\dfrac{width \ stain}{length \ stain} )}](https://tex.z-dn.net/?f=%5Cmathbf%7BAngle%20%20%5C%20of%20%5C%20%20impact%20%3D%20sin%5E%7B-1%7D%20%28%5Cdfrac%7Bwidth%20%5C%20stain%7D%7Blength%20%5C%20stain%7D%20%29%7D)
![\mathbf{Angle \ of \ impact = sin^{-1} (\dfrac{1.5}{3.0} )}](https://tex.z-dn.net/?f=%5Cmathbf%7BAngle%20%20%5C%20of%20%5C%20%20impact%20%3D%20sin%5E%7B-1%7D%20%28%5Cdfrac%7B1.5%7D%7B3.0%7D%20%29%7D)

Answer:
1440°
Step-by-step explanation:
n = number of sides
n-2 x 180
10 - 2 = 8
8 x 180 = 1440°
The full price is $82, (100%), the discounted price is $65.60, (?%)
So lets see something:
$82 ------------- 100%
$65.60 --------------- x%
Multiply in cross
82.x = 65,60 . 100
82x = 6560
Divide both sides by 82
82x/82 = 6560/82
x = 80
So the discounted price is equal to 80% of the initial price
100% - 80% = 20% so the discount is 20%
