Math Problem Statement
Solution
To find the height of the building, we can use similar triangles. Since the pole and its shadow form a triangle with the sun, and the building and its shadow form a similar triangle with the same angle of sunlight, the ratios of corresponding sides of these triangles will be equal.
Given:
- Height of the pole
- Shadow of the pole
- Shadow of the building
Let be the height of the building.
Using the similarity of the triangles:
Substitute the known values:
Now, solve for :
-
Cross multiply:
-
Simplify:
-
Divide by 1.64 to find :
-
Calculate :
Rounding to the nearest meter, the height of the building is approximately .
