Answer:
Step-by-step explanation:
Let the height of the tower is a and the shadow is b.
When connected, these segments form a right triangle.
We are looking for the angle x opposite to side a.
Use trigonometry to find it:
- tan x = a/b
- tan x = 125/172
- tan x = 0.7267
- x = arctan 0.7267
- x = 36°
