The length of a shadow of a building is 28m. The distance from the top of the building to the shadow is 38m. Find the height of

AlexFokin [52]

It appears that the Pythagorean theorem can be applied to this problem
(distance to shadow)² = (height of building)² + (length of shadow)²
(38 m)² = (height of building)² + (28 m)²
660 m² = (height of building)²
Then the height of the building is
height of building = √660 m ≈ 25.7 m
