Question

A triangle is formed by the building's height

and shadow. Another triangle is formed by
the flagpole's height and shadow. Using the
following diagram, find the height of the
building.

Answer 1

Answer: 400 ft

Explanation:

Since the triangles are Congruent Triangles (similar)

x/40 = 50/5

Cross multiply

5x = 2000

divide both sides by 5

5x/5 = 2000/5

x = 400 ft
