Answer:
The person is 6 feet tall
Explanation:
The height of the buiding = 100 feet
The shadow cast by the building = 25 feet
Let the angle of the sun in the sky be represented by θ
The height of person = t
The shadow cat by the person = 1.5 feet
These can be descibed diagrammatically as shown below
From the diagrams:
[tex]\begin{gathered} \tan \theta\text{ = }\frac{100}{25}\ldots\ldots\ldots(1) \\ \tan \theta=\frac{t}{1.5}\ldots\ldots\ldots\text{.}(2) \end{gathered}[/tex]
Comparing equations (1) and (2)
[tex]\begin{gathered} \frac{100}{25}=\text{ }\frac{t}{1.5} \\ 4\text{ = }\frac{t}{1.5} \\ t\text{ = 4(1.5)} \\ t\text{ = }6 \end{gathered}[/tex]
The person is 6 feet tall
