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
