In a film, the 555-ft-tall Washington Monument casts a 100-feet-long shadow, whereas the main character in the film casts a 4-feet-long shadow nearby. This is considered a film "goof" because the proportion is not realistic. How tall would the main character be according to the given measurements?

Round to the nearest whole foot.

Solution:

The height of the main character be according to the given measurements is X.

According to the theory of similar triangle,

We have the following equation:

555/100 = X/4

X = 22.2

So the main character is 22.2 ft tall, which is not realistic
