Windows media player should come pre-installed on your system and does not cost anything. You likely have malware on your system. I would download Malwarebytes antimalware from here

There is a premium version but just do the free one. Install and run. Let it get rid of the bad stuff it finds. I would also make sure you have an up to date Antivirus software and run a scan. There are plenty of good free ones if you don't have one installed already.
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:
Bandwidth describes the maximum data transfer rate of a network or Internet connection. ... For example, a gigabit Ethernet connection has a bandwidth of 1,000 Mbps (125 megabytes per second). An Internet connection via cable modem may provide 25 Mbps of bandwidth.
You actually have the correct answer. An excel formula starts with = so your answer would be =4*6
