Answered below.
Explanation:
This answer is applicable to Linux.
There are several commands for copying files in Linux. cp and rsync are the most widely used. cp though, is the command used to copy files and their contents.
To copy a file named report1.txt to another file named report1uc.txt in the current directory, the following command is run.
$ cp report1.txt report1uc.txt
You can change the case of the strings in the file by using the tr command.
tr [:lower:] [:upper:]
For example,
$ echo brainly | tr [:lower:]. [:upper:]
Result is BRAINLY.

the answer should be the letter a
Answer:
The program to this question can be given as:
Program:
#include <stdio.h> //include header files
#include<math.h>
int main() //main method
{
double treeHeight = 0.0; //declare variables
and assign value
double shadowLength = 0.0;
double angleElevation = 0.11693706;
// (0.11693706 radians = 6.7 degrees) convert number into angle.
shadowLength = 17.5;
treeHeight = shadowLength * tan(angleElevation); //convert number into angle
printf("Tree height: %lf\n", treeHeight); //print value.
return 0;
}
Output:
Tree height: 2.055778
Explanation:
In the above C language program firstly we include the headers. In this header file, we include a (math.h) header file this file helps to use the math function. Then we declare the main method in the main method we declare the variable that is given in the question that are treeHeight, shadowLength , angleElevation. All the variable datatype is double because it stores the floating-point value. Then we apply the formula that is treeHeight = shadowLength * tan(angleElevation). In this formula, the treeHeight variable holds the value. Then we print the variable value for print the double value we use the lf(that is long float).
