In python :
simple geometry can compute the height of an object from the object's shadow length and shadow angle using the formula:
tan(angleelevation) = tree_height / shadow_length. given the shadow length and angle of elevation, compute the tree height.
sample output with inputs: 0.4 17.5
tree height: 7.398881327917831

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
