What is proportion?
A proportion is an equation in which two ratios are set equal to each other.
According to the question
A water tower casts an 100 ft shadow. At the same time a 8 ft street sign casts a 6 ft shadow.
From the figure, we can write
Using proportion,
AD : AB = AE : AC
8 : x = 6 : 100
[tex]\frac{8}{x}= \frac{6}{100}[/tex]
[tex]x=\frac{8 \times 100}{6}[/tex]
[tex]x = 133.34 \ foot[/tex]
Height of the tower is 133.34 foot.
