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.

tan(angleElevation) = tree height / shadow length\\\\tree height = tan(angleElevation) * shadow length

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

<h2>Question</h2>

Which of the following class definition defines a legal abstract class Group of answer choices

(a)

public class Rectangle abstract {

   public abstract double findArea ( );

   

}

(b)

public abstract class Rectangle {

   public abstract double findArea ( );

   

}

(c)

public class Rectangle {

   public abstract double findArea ( );

   

}

(d)

public class abstract Rectangle {

   public abstract double findArea ( );

   

}

<h2>Answer:</h2>

(b)

public abstract class Rectangle {

   public abstract double findArea ( );

}

<h2>Explanation:</h2>

When a class is declared with the abstract keyword, the class is called an abstract class. Abstract classes cannot be instantiated and may include one or more abstract methods. If a class contains an abstract method, then it (the class) must be declared abstract.

In Java, abstract classes are defined using the following format:

<em>[access_modifier]</em> abstract class <em>[name_of_class]</em>

[access_modifier] specifies the access modifier of the class which could be public, private, e.t.c

abstract is the keyword that specifies that the class is an abstract class.

class is a keyword used for defining classes

name_of_class specifies the name of the class.

The only option that fulfils this format is <em>option b</em> where;

(i) The access modifier is public

(ii) The name of the class is Rectangle

Option a is not correct because the <em>abstract</em> keyword is supposed to come before the <em>class</em> keyword.

Option c is not correct because the keyword <em>abstract</em> is missing. In other words, the class must be declared abstract since it contains abstract method findArea();

Option d is not correct because the <em>abstract</em> keyword is supposed to come before the <em>class</em> keyword.

What is a digital certificate? Select one: a. It is a means of establishing the validity of an offer from a person, entity, web
a_sh-v [17]

Option D is the answer because Digital Certificate is an entity that generates electronic and distributes them upon proving their identity sufficiently. In early days there was issues with people using the certificates that were not even issued by the organizations. Today it's a cryptographic technique which uses digital signatures and gives users a digital certificate that can be authenticated anytime online by any organization and is unique for every user having it.

Option A cannot be the answer because it has nothing to do with the identity of person but rather it is for specific fields.

Option B is not answer because it has no key and score matter to do with it.

Option C Web transactions has nothing to do with the certificates.
