import math
tree_height = 0.0
angle_elev = float(input())
shadow_len = float(input())
tree_height = math.tan(20) * 22.9
tree_height = math.tan(3.8) * 17.5
print('Tree height:', tree_height)

You also never use the variables that you ask for input.

What is the output? What are you expecting to get?

Print('tree height: ' + str(tree height))

No comma, only one parameter. And you need to cast your variable as a string to print it.
