Answer:
import math
angle = float(input('Enter Angle: '))
shadowLength = float5(input('Enter Shadow Length: '))
tree_height = math.tan(angle)*shadowLength
print('Tree Height = {}'.format(tree_height))
Explanation:
From the equation given, the first step is to derive the equation for calculating the Tree Height.
In order to calculate the tangent of an angle, the math module has to be imported. math module allows the program to perform advanced math operations.
The program then prompts the user to input values for angle and shadow length.
The inputted values are converted to floats and used in the equation that was derived for Tree height.
Three height is evaluated and the result is printed to the screen
Answer:
A primary key is a special relational database table column (or combination of columns) designated to uniquely identify each table record. A primary key is used as a unique identifier to quickly parse data within the table. A table cannot have more than one primary key.
Primary Key.
Candidate Key.
Alternate Key.
Super Key.
Composite Key.
Foreign Key.
Unique Key.
In the relational model of databases, a primary key is a specific choice of a minimal set of attributes that uniquely specify a tuple in a relation. Informally, a primary key is "which attributes identify a record," and in simple cases constitute a single attribute: a unique ID.

Mostly the spyware and malware protection for desktop and laptop or workstations are to protected with anti-virus regular updates. All workstation or desktop or laptops are to updated operating systems patches.
If any operating systems patched update to be schedule and checked regularly. Schedule scanning by virus scanner to be made for desktop and laptop or workstations in regular interval basis
There are third parties tools such as malware and ADWCLEANER are also available free scanner software through internet where end user can download and scanner so software will clean the malware.
Mostly end user do mistake keep the files in desktop. Most of the malware software will affect the desktop folder only.
It will also affect c:\users folder and register enter keys.
It's neat organized and ready to find when needed
