Answer:
The height of the building is 2√165 (m)
Step-by-step explanation:
You can imagine that the distance from the top of the building to the tip of the shadow is like hypotenuse, the length of a shadow of a building is like squared angle edge
Assume the height of the building is x
According to Pythagorean theorem:
28^2 + x^2 = 38^2
x^2 = 38^2 - 28^2
x = √(38^2 - 28^2)
x= 2√165 (m)
